Updated mediawiki/extensions
Project: mediawiki/extensions/Teahouse  6abb4f2266ab480946928f64931fac377d47c8c9

Moved OOJS UI components to separate file

Also added some new config variables

The goal is to have smaller files for better maintainability.
Unfortunately this doesn't go well with the idea of a MediaWiki gadget
