Documented a bit of HumanoidModel and changed some number to their GL Constants
Made it so the player class uses its getModel() when rendering its model now.
Documented Entity a bit more, cleaned it up a bit, and removed unused variables from some methods in it.
Formatted a bit.
More Javadocs + Refactored some boolean names using is (isFullScreen, isWaiting, etc)
I just noticed this is needed to allow the player to be rendered as a different model.
Changed some key ints to their constants.
Forgot the Escape key.
Merge pull request #168 from Gamemakergm/master

Added some Java Docs, cleanup, and some variable renaming.
