[Foundation-l] Editable wiki-wide stylesheets

[Tim Starling]

Thanks to Gabriel Wicke, sysops can now add a stylesheet for their wiki 
using [[MediaWiki:Monobook.css]]. The content of these stylesheets 
should be similar to the user stylesheets. I have used this feature to 
increase the font size on the CJK wikis, as requested on wikitech-l. 
Stylesheets for the other skins and configurable javascript will be 
implemented soon.
