Project: mediawiki/skins/BlueSky  505b47a35428a6cf5b51042d3dacf17223522f0d

Content header style stuff

Format header, add ToC (stolen from refreshed skin)
Format some other random things - content, button placement, etc
Add special mainpage formatting
Possibly other stuff.

Needs cleaning up and integration into the skin itself (basically just tacked on the end)
