* (bug 15558) Allow includable special pages to be parameterized using wiki syntax
* Changed SpecialPageFactory::capturePath() to take the same parameters as SpecialPageFactory::executePath() (except the last one) and made it always return a bool instead of bool-or-string. The result HTML can be fetched from the OutputPage object of the context.
* Added module styles, scritps and messages members to ParserOutput in addition to modules. The first one is needed to display Special:RecentChanges correctly when transcluded since EnhancedChangesList::beginRecentChangesList() calls addModuleStyles( 'mediawiki.special.changeslist' )
Yes, this means that you can use {{Special:Recentchanges|enhanced=0}} to use the old changes list. For the ones that wonder, {{Special:Recentchanges|uselang=something}} will not work since the Language object is forced to the one used by the parser.
