-Rewritten KinematicBody2D::move to MUCH more efficient code.

-KinematicBody2D::move now properly recognizes collision exceptions and masks, fixes #1649
-Removed object type masking for KinematicBody2D
-Added a test_motion() function to RigidBody2D, allowing simlar behavior to KinematicBody2D::move there.
