PhysicsShape library almost complete

Only Box intersect Ellipse to go.
Finished the collision detection methods, now to implement
Seems to still work :P
Done for now, need to add PhysicsClasses to Entities

PhysicsClasses will determine what collides with what and what events
take place on collision
Collision detection is working

Couple bugs.
One what is the ring of bullets that appears when the time passes
integers?
Two why does collision detection not work properly with time rewind?

Plans:
rework the time system to use GameEvents or sth like that.
