88897cc744 implement pybullet.changeTexture. For now, the width/height has to match the target texture unique id, otherwise crashes may happen (a check for width/height match will be added)

bf800e30d5 Added manually converted widowx.urdf from https://github.com/RobotnikAutomation/widowx_arm
Added simple pybullet file in Bullet/examples/pybullet/examples/widows.py (preliminary, both URDF and py file needs more work to be useful)

fix in b3HashString
remove many unused dependencies from kuka_grasp_block_playback.py (time,math, datetime ,numpy,pylab ,sys, os, fnmatch,argparse were not used!)
move block_grasp_log.bin from Bullet3/data to Bullet3/examples/pybullet/examples/data folder.

b645963879 expose pybullet changeDynamics(spinningFriction=..., rollingFriction=..., restitution=...)
Bullet C-API b3ChangeDynamicsInfoSetSpinningFriction/RollingFriction/Resitution
b3PhysicsParamSetRestitutionVelocityThreshold, / pybullet.setPhysicsEngineParameter restitutionVelocityThreshold:
if the velocity is below this threshhold, the restitution is zero (this prevents energy buildup at near-resting state)
pybullet restitution.py example.
