This adds extensive support for soft-bodies in Rapier. This includes shape-matching, constraints-based deformations, FEM, tearing, plasticity (= permanent deformations), cloths, kinematic control, deformable sensors, impulse joints attached to soft-bodies, etc.

I will update the user-guide and post a detailed technical description about this shortly (probably in a week or two). In the mean time, feel free to play around with the soft-bodies example on the testbed, and here are a few screenshots:
