Updated mediawiki/skins
Project: mediawiki/skins/BlueSky  600f98b00b86949b3576a334101c1200f249e385

* General code cleanup all over the place
* Removed hard-coded bits 'n' pieces specific to wikiHow's social extensions
* commonInterface.css is now loaded by the skin so that the orange bar of death is actually orange etc.
* Gave div#bodycontents class="minor_section" so that it gets the necessary white background
