		 * morebits.js
		 * ===========
		 * A library full of lots of goodness for user scripts on MediaWiki wikis, including Wikipedia.
		 *
		 * The highlights include:
		 *   - Morebits.quickForm class - generates quick HTML forms on the fly
		 *   - Morebits.wiki.api class - makes calls to the MediaWiki API
		 *   - Morebits.wiki.page class - modifies pages on the wiki (edit, revert, delete, etc.)
		 *   - Morebits.wikitext class - contains some utilities for dealing with wikitext
		 *   - Morebits.status class - a rough-and-ready status message displayer, used by the Morebits.wiki classes
		 *   - Morebits.simpleWindow class - a wrapper for jQuery UI Dialog with a custom look and extra features
		 *
		 * Dependencies:
		 *   - The whole thing relies on jQuery.  But most wikis should provide this by default.
		 *   - Morebits.quickForm, Morebits.simpleWindow, and Morebits.status rely on the "morebits.css" file for their styling.
		 *   - Morebits.simpleWindow relies on jquery UI Dialog (ResourceLoader module name 'jquery.ui').
		 *   - Morebits.quickForm tooltips rely on Tipsy (ResourceLoader module name 'jquery.tipsy').
		 *     For external installations, Tipsy is available at [http://onehackoranother.com/projects/jquery/tipsy].
		 *   - To create a gadget based on morebits.js, use this syntax in MediaWiki:Gadgets-definition:
		 *       * GadgetName[ResourceLoader|dependencies=mediawiki.user,mediawiki.util,jquery.ui,jquery.tipsy]|morebits.js|morebits.css|GadgetName.js
		 *
		 * Most of the stuff here doesn't work on IE < 9.  It is your script's responsibility to enforce this.
		 *
		 * This library is maintained by the maintainers of Twinkle.
		 * For queries, suggestions, help, etc., head to [[Wikipedia talk:Twinkle]] on English Wikipedia [http://en.wikipedia.org].
		 * The latest development source is available at [https://github.com/azatoth/twinkle/blob/master/morebits.js].

		/**
		 * **************** Morebits.wiki.page ****************
		 * Uses the MediaWiki API to load a page and optionally edit it, move it, etc.
		 *
		 * Callers are not permitted to directly access the properties of this class!
		 * All property access is through the appropriate get___() or set___() method.
		 *
		 * Callers should set Morebits.wiki.actionCompleted.notice and Morebits.wiki.actionCompleted.redirect
		 * before the first call to Morebits.wiki.page.load().
		 *
		 * Each of the callback functions takes one parameter, which is a
		 * reference to the Morebits.wiki.page object that registered the callback.
		 * Callback functions may invoke any Morebits.wiki.page prototype method using this reference.
		 *
		 *
		 * NOTE: This list of member functions is incomplete.
		 *
		 * Constructor: Morebits.wiki.page(pageName, currentAction)
		 *    pageName - the name of the page, prefixed by the namespace (if any)
		 *               (for the current page, use mw.config.get('wgPageName'))
		 *    currentAction - a string describing the action about to be undertaken (optional)
		 *
		 * load(onSuccess, onFailure): Loads the text for the page
		 *    onSuccess - callback function which is called when the load has succeeded
		 *    onFailure - callback function which is called when the load fails (optional)
		 *
		 * save(onSuccess, onFailure): Saves the text for the page. Must be preceded by calling load().
		 *    onSuccess - callback function which is called when the save has succeeded (optional)
		 *    onFailure - callback function which is called when the save fails (optional)
		 *    Warning: Calling save() can result in additional calls to the previous load() callbacks to
		 *             recover from edit conflicts!
		 *             In this case, callers must make the same edit to the new pageText and reinvoke save().
		 *             This behavior can be disabled with setMaxConflictRetries(0).
		 *
		 * append(onSuccess, onFailure): Adds the text provided via setAppendText() to the end of the page.
		 *                               Does not require calling load() first.
		 *    onSuccess - callback function which is called when the method has succeeded (optional)
		 *    onFailure - callback function which is called when the method fails (optional)
		 *
		 * prepend(onSuccess, onFailure): Adds the text provided via setPrependText() to the start of the page.
		 *                                Does not require calling load() first.
		 *    onSuccess - callback function which is called when the method has succeeded (optional)
		 *    onFailure - callback function which is called when the method fails (optional)
		 *
		 * getPageName(): returns a string containing the name of the loaded page, including the namespace
		 *
		 * getPageText(): returns a string containing the text of the page after a successful load()
		 *
		 * setPageText(pageText)
		 *    pageText - string containing the updated page text that will be saved when save() is called
		 *
		 * setAppendText(appendText)
		 *    appendText - string containing the text that will be appended to the page when append() is called
		 *
		 * setPrependText(prependText)
		 *    prependText - string containing the text that will be prepended to the page when prepend() is called
		 *
		 * setEditSummary(summary)
		 *    summary - string containing the text of the edit summary that will be used when save() is called
		 *
		 * setMinorEdit(minorEdit)
		 *    minorEdit is a boolean value:
		 *       true  - When save is called, the resulting edit will be marked as "minor".
		 *       false - When save is called, the resulting edit will not be marked as "minor". (default)
		 *
		 * setBotEdit(botEdit)
		 *    botEdit is a boolean value:
		 *       true  - When save is called, the resulting edit will be marked as "bot".
		 *       false - When save is called, the resulting edit will not be marked as "bot". (default)
		 *
		 * setPageSection(pageSection)
		 *    pageSection - integer specifying the section number to load or save. The default is |null|, which means
		 *                  that the entire page will be retrieved.
		 *
		 * setMaxConflictRetries(maxRetries)
		 *    maxRetries - number of retries for save errors involving an edit conflict or loss of edit token
		 *    default: 2
		 *
		 * setMaxRetries(maxRetries)
		 *    maxRetries - number of retries for save errors not involving an edit conflict or loss of edit token
		 *    default: 2
		 *
		 * setCallbackParameters(callbackParameters)
		 *    callbackParameters - an object for use in a callback function
		 *
		 * getCallbackParameters(): returns the object previous set by setCallbackParameters()
		 *
		 *    Callback notes: callbackParameters is for use by the caller only. The parameters
		 *                    allow a caller to pass the proper context into its callback function.
		 *                    Callers must ensure that any changes to the callbackParameters object
		 *                    within a load() callback still permit a proper re-entry into the
		 *                    load() callback if an edit conflict is detected upon calling save().
		 *
		 * getStatusElement(): returns the Status element created by the constructor
		 *
		 * setFollowRedirect(followRedirect)
		 *    followRedirect is a boolean value:
		 *       true  - a maximum of one redirect will be followed.
		 *               In the event of a redirect, a message is displayed to the user and
		 *               the redirect target can be retrieved with getPageName().
		 *       false - the requested pageName will be used without regard to any redirect. (default)
		 *
		 * setWatchlist(watchlistOption)
		 *    watchlistOption is a boolean value:
		 *       true  - page will be added to the user's watchlist when save() is called
		 *       false - watchlist status of the page will not be changed (default)
		 *
		 * setWatchlistFromPreferences(watchlistOption)
		 *    watchlistOption is a boolean value:
		 *       true  - page watchlist status will be set based on the user's
		 *               preference settings when save() is called
		 *       false - watchlist status of the page will not be changed (default)
		 *
		 *    Watchlist notes:
		 *       1. The MediaWiki API value of 'unwatch', which explicitly removes the page from the
		 *          user's watchlist, is not used.
		 *       2. If both setWatchlist() and setWatchlistFromPreferences() are called,
		 *          the last call takes priority.
		 *       3. Twinkle modules should use the appropriate preference to set the watchlist options.
		 *       4. Most Twinkle modules use setWatchlist().
		 *          setWatchlistFromPreferences() is only needed for the few Twinkle watchlist preferences
		 *          that accept a string value of 'default'.
		 *
		 * setCreateOption(createOption)
		 *    createOption is a string value:
		 *       'recreate'   - create the page if it does not exist, or edit it if it exists
		 *       'createonly' - create the page if it does not exist, but return an error if it
		 *                      already exists
		 *       'nocreate'   - don't create the page, only edit it if it already exists
		 *       null         - create the page if it does not exist, unless it was deleted in the moment
		 *                      between retrieving the edit token and saving the edit (default)
		 *
		 * exists(): returns true if the page existed on the wiki when it was last loaded
		 *
		 * lookupCreator(onSuccess): Retrieves the username of the user who created the page
		 *    onSuccess - callback function which is called when the username is found
		 *                within the callback, the username can be retrieved using the getCreator() function
		 *
		 * getCreator(): returns the user who created the page following lookupCreator()
		 *
		 * getCurrentID(): returns a string containing the current revision ID of the page
		 *
		 * patrol(): marks the page as patrolled, if possible
		 *
		 * move(onSuccess, onFailure): Moves a page to another title
		 *
		 * deletePage(onSuccess, onFailure): Deletes a page (for admins only)
		 *

		 *
		 * Constructor: Morebits.batchOperation(currentAction)
		 *
		 * setPageList(wikitext): Sets the list of pages to work on.
		 *    It should be an array of page names (strings).
		 *
		 * setOption(optionName, optionValue): Sets a known option:
		 *    - chunkSize (integer): the size of chunks to break the array into (default 50).
		 *                           Setting this to a small value (<5) can cause problems.
		 *    - preserveIndividualStatusLines (boolean): keep each page's status element visible
		 *                                               when worker is complete?  See note below
		 *
		 * run(worker): Runs the given callback for each page in the list.
		 *    The callback must call workerSuccess when succeeding, or workerFailure
		 *    when failing.  If using Morebits.wiki.api or Morebits.wiki.page, this is easily
		 *    done by passing these two functions as parameters to the methods on those
		 *    objects, for instance, page.save(batchOp.workerSuccess, batchOp.workerFailure).
		 *    Make sure the methods are called directly if special success/failure cases arise.
		 *    If you omit to call these methods, the batch operation will stall after the first
		 *    chunk!  Also ensure that either workerSuccess or workerFailure is called no more
		 *    than once.
		 *
		 * If using preserveIndividualStatusLines, you should try to ensure that the
		 * workerSuccess callback has access to the page title.  This is no problem for
		 * Morebits.wiki.page objects.  But when using the API, please set the
		 * |pageName| property on the Morebits.wiki.api object.
