Removed potential for any type of unit stacking - buildings and units can't even be on the same tile. Maybe in the future in version 2 or something
Began work on the TBS Engine
Added a GUIButton class that makes it easy to add buttons to the interface
Now you can buy and place units :-) Need better art though
Added a game_state module that has a game variable in it. To use it, just import game_state, then call game_state.game to use it
