BulletSim: do not zero an avatar's standing velocity if it is standing
on a moving object. Rearrange pre/post action subscription code to put more in locks. Add meshmerizer params to BulletSimTestUtil scene creation (and fix line endings). Rebuilt version of DLLs and SOs with cleaned up code and no profiling for sure.
