Added MirrorSystem

This is really just for letting one sprite mirror another's movement and animation. I tried doing it in the BehaviourSystem, but you get stuttering if you do it earlier in the loop than the CharacterSystem, so I ended up having to make a new system just for this thing that will not happen very often.
