work on pybullet/C-API createMultiBody (still preliminary, only sphere/box collision shapes, no links/hierarchies yet, soon)

Browse Source 
pybullet/C-API, expose linear/angular damping
fix some warnings (param name needs to be same in .h and .cpp)
fix potential startup threading issue (args were deleted in main thread while still possibly use in child thread)
fix for spinning/rolling friction in case of mixing maximal and reduced coordinate btMultiBody+btRigidBody
