Added unlockable doors and prop physics
Changed ordering of physics collision handling
Buttons position is now proportional to screen size and sounds stop on new game state
Added Potions that restore the players health.
Currently the potions spawn in hallways and sometimes spawn on top of doors, because I'm not quite sure how to spawn them in the middle of a room.
