Changes to 2D physics engine

-=-=-=-=-=-=-=-=-=-=-=-=-=-=

-Removed "density" property
-Added instead more flexible "angular damp" and "linear damp"
-Added ability to override angular and linear damp in rigidbody
-Added gravity scale option rigidbody

Test well and iron out bugs, when it works the same will be moved to 3D
