Loads the templatestyles for the infobox.
TODO: load base templatestyles here rather than in MediaWiki:Common.css
We aren't doing it here yet because there are 4-5000 pages with 'raw' infobox
tables. See [[Mediawiki_talk:Common.css/to_do#Infobox]] and/or come help :).
When we do this we should clean up the inline CSS below too.
Will have to do some bizarre conversion category like with sidebar.
