* Incorporated tree display into the default category page view
* Implemented memcached caching for ajax requests with invalidation via page_touched * General refactoring, moved some global functions into a class * Lazy initialisation of messages, initialise the <head> section in the output only when a categorytree tag is present. * Eliminated all $wgUser and $wgLang accesses from ajax requests, using message placeholders. * Added speak:none style in .CategoryTreeBullet in case voice browsers try to read out the punctuation
