Improved default styling

* This styling is a bit less intrusive. I would imagine in most cases people are going to tweak borders, font size, etc to match their site style. Removing explicit definitions makes it easier to integrate into an existing design.
* Instead of the red stars, the CSS positions the gifs to the gold stars, which are more visually pleasing.

Hopefully this could be easily applied to other branches. Right now I'm still stuck on 1-3 :(
