Skill Animations added
Changed testing skills back to what they were plus minor formatting.
Minor code formatting.
Moved GameLoop.window to GL.WINDOW plus more preparation for pause menu implementation.
Input object no longer passed to Player during creation, GameLoop's accesses Input objects via GL.INPUT1 or GL.INPUT2, Player objects self.input now points to the appropriate GL.INPUT, Monster class self.input points to an internal self.ai_input.
More progress toward pause menu - properly calls pause menu and returns from it.
Reorganization of GameLoop.__init__.
Slight simplification of Player instantiation.
Added icons and particle visuals... took forever
Resynced to most recent upstream with mines
Made dropped skill icons show the actual skill icons

Fixed some bugs
