trunk updates with themeroller


After talking with Richard about it, FG will begin making some commits
to trunk for the next version of ThemeRoller today. This will include
the new framework classes, CSS sprite support for icons, and animated
animated gif theming, among other things. This will all need to be
matched with updates to all the widget markup so they use framework
classes, as well as additional elements wherever needed for icons.
These changes will be incompatible with the live ThemeRoller site, so
if you need to make minor changes to the current ThemeRoller CSS to
fix a bug or anything, please make a branch at r969.
