Fix HP bar animation
Previously, the HP bar would change color while animating, which
actually looks pretty cool but unfortunately was sort of buggy, and
also has a noticeable performance impact because jQuery animation
isn't exactly fast.

This changes the HP bar to change color after animating instead,
which still looks good but is a lot simpler.
