Support raw html ouput from extension [edit]
| Extensions such as charinsert and User:Joncutrer/Extensions/Google Adsense Search generate raw html, which could be broken by other parser process. | CharInsert 插件 和 搜索引擎插件 直接生成 Raw HTML 代码，但是这些插件生成的 Raw HTML 代码并非像内置的 <html> 或者 <pre> 那样受到良好的支持。可能受到 Parser 的其它步骤的影响，导致输出和预期不符。 |
| The following patch give extension hacker a chance to treat their extension's raw html output just as what <html>, or <pre> does. | 下面的插件给开发者提供一个选项，使得 raw html 类型的插件如同系统默认的 raw html 插件一样。 |

How a extension can benefit from this feature? For example, extension charinsert only needs to add the new global function 'wfRawHtmlTag' in it's hook.
