c4b1b84687 Enable 'global absolute velocities' by default for btMultiBody. See 8.3.2B Proposed resolution Jakub Stepien PhD Thesis
https://drive.google.com/file/d/0Bz3vEa19XOYGNWdZWGpMdUdqVmZ5ZVBOaEh4ZnpNaUxxZFNV/view?usp=sharing
Fixes crashes due to rendering of softbody wireframe in the wrong thread (needs to be in 'debug' rendering section)
Use btCapsuleShapeZ instead of btMultiSphereShape when converting MJCF MuJoCo capsules using fromto

c59a3763e5 tweak ImportMJCFSetup.cpp example MJCF humanoid a bit, clamp target positions to be within joint limits to avoid solver problems (conflicting constraints)

79d78a325a Start of a urdfEditor.py, limited support to extract a URDF from a PyBullet body.
Use btCylinderShapeZ for URDF cylinder, instead of converting it to a btConvexHullShape.
Implement PyBullet.getCollisionShapeData
Extend PyBullet.getDynamicsInfo / b3GetDynamicsInfo, remove flag (don't rely on API returning a fixed number of elements in a list!)
Extend PyBullet.getJointInfo: add parentIndex

0326fa93a8 made some progress in saving and restoring the state during the simulation, with identical results.
Option to de/serialize btPersistentContactManifolds and fix lossy conversion during btMultiBody de/serialization of base world transform
(serialize the quaternion, not the converted 3x3 matrix)
There are still several caches not taken into account, and btMultiBody links/constraints are not deserialized yet etc.
See examples\pybullet\examples\saveRestoreState.py for an example.
