TinyMCE_MW.php - MediaWiki extension - version 0.5.4
        by Joseph P. Socoloski III
        If you already have pages written in Mediawiki wikitext, this extension enables
        Moxiecode's TinyMCE and does not break Mediawiki wikitext. Also, TinyMCE_MW 
        has a new 'msword' configuration theme.  msword follows the MS Office 2003
        toolbar layout. Call TinyMCE's simple, advanced and a built-in msword theme from 
        LocalSettings.php.  TinyMCE_MW was built and tested on Mediawiki-1.10.0.  
        Successfully tested CategoryTree extension for compatibility with new tags.
		-Improved custom tag parsing for repeat and categorytree; added sql2wiki

        NOTE:To change the default font and size for TinyMCE, add these two lines to your
        theme's editor_content.css body{} section:
        font-family: Arial;
        font-size: 14px;
        NOTE:To decrease the space between lines after a carriage return place this line 
        to your theme's editor_content.css:
        p {margin: 0; padding: 0;}           
BUGS:   - Does not support Wikitext Bullet list
                - Does not support Wikitext Numbered list
                - Does not support Wikitext Redirect to another article
