Merging resourceloader branch into trunk. Full documentation is at http://www.mediawiki.org/wiki/ResourceLoader and a general overview has been posted on wikitech-li <http://lists.wikimedia.org/pipermail/wikitech-l/2010-September/049253.html>. One important change is that all JS is now loaded at the bottom, so any scripts assuming things from wikibits or whatever are present will fail.
