* UI: Better status bar animations
This is an alternate implementation of #2286. It does the same
wrap-around behaviour for when the progressbar crosses into the next
level, but it skips animation entirely if the effective skill level goes
down, or if more than one level is gained at a time.
The implementation uses the animate() DOM api instead of manipulating
styles, which completely avoids the issues of having CSS style buildup.
This API is designed for exactly what we're trying to do.
I also pushed rerender handling down from CharacterOverview to
StatsProgressBar, which simplifies things and is helpful for doing the
animation implementation.
