Worked on moving some of wikiHow's skin-specific PHP core hacks to the skin, and had to learn how LESS works because this is one of those situations where using LESS makes a lot of sense. Nothing to commit yet.
Updated MediaWiki core from 1.22alpha to 1.24alpha, thanks legoktm!
Added BlueSky to the Labs wiki for testing.
Discovered several issues with it on 1.24alpha/master, of which the most critical (see below) I was able to fix right away. The skin's main JS file is broken, because $.browser is undefined (!) in whatever version of jQuery 1.24alpha "ships" with.
Use accessor function for accessing OutputPage::$mCategoryLinks as it's a protected property in MW 1.24/master. (gerrit:147002)
