Makes the API for forces and impulses more flexible, easier to understand and harmonized between 2D and 3D. Rigid bodies now have 3 sets of methods for forces and impulses: -apply_impulse() for impulses (one-shot and time independent) -apply_force() for forces (time dependent) applied for the current step -add_constant_force() for forces that keeps being applied each step Also updated the documentation to clarify the different methods and parameters in rigid body nodes, body direct state and physics servers.
