Fix T43406: Bring back cloth collisions.

Browse Source 
This was disabled during the course of hair dynamics work. The cloth
collision solution is based on a secondary velocity-only solver step.

While this approach is usable in general, the collision response
calculation still does not work well for hair meshes. Better contact
point generation is needed here (Bullet) and preferably an improved
solver for unilateral constraints.
