Another Facemaker update

I've updated the FaceMaker applet with the following changes:

  1. Added hover text-tips for the buttons to show what they do.
  2. Added a "color hair" button that does the same thing for hair, mustache, and beard as the "color skin" button.
  3. Changed the color of the item slot boxes to match the other buttons' color schemes.

The last two big things to do are to a) add the preview boxes over on the right (bleh) and b) get the final "skin" designed and implemented. Should be relatively soon!
