Gamefile changes

No one said "no" to the beatrix concept art, so I put her in. Also, I
made some major tweaks to the code:

*cleaned up global variables that are no longer needed
*cleaned up use of global variables to be self.WhateverTheyAreCalled
*changed properties of beatrix
*added Human and Werewolf properties to Beatrix
*cleaned up crouch a little
*acceleration is a tab bit better
*added comments to code

STILL NEED COMMENTS IN A FEW AREAS THAT I DO NOT UNDERSTAND

It's looking good so far!
