Forum:Infobox formatting

Currently, all of our (new) infoboxes have curved corners in some browsers (like Chrome) and rectangular corners in other browsers (like the latest Firefox). This is because they lack the  property. The obvious choice here is to simply add  to every infobox, but I think this is a good chance to rethink that scheme. The sharp edges of the header of every infobox contrasts with the soft edges of the infobox itself, which I've never been fond of (this is also the way they have it on the TO Wiki). If you'll head over to w:c:fortesting:User:Dzylon/infoboxexample, you'll see two alternatives. In one, we simply leave the infoboxes as boxes (no curved corners). In another, the header's top-right and top-left corners are modified to match the border-radius version of the infobox. Thoughts?

Also (and this is a smaller thing) all of our infoboxes are using the infobox class while overriding most of the properties. This could be a good chance to simplify those templates and update our Mediawiki:Common.css.
