79051b7611 allow to use colors from MJCF file as option (default to random Google colors), use p.loadMJCF(filename, flags=p.URDF_MJCF_COLORS_FROM_FILE 
fix quadruped.py example.
add PyBullet.isConnected() API, more friendly than PyBullet.getConnectionInfo()["connected"]

22b4809891 leave m_useGlobalVelocities to false, until enabled, for backward compatibility 
use URDF_GLOBAL_VELOCITIES_MB flag in PyBullet loadURDF.
fix robot_bases.py due to new fields in getJointInfo.
backward compabitibility: BulletMJCFImporter, keep creating btMultiSphereShape for MJCF capsules with fromto, instead of shifted btCapsuleShapeZ, unless if CUF_USE_IMPLICIT_CYLINDER is used.

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) 
add humanoid_manual_control.py PyBullet example which is similar to ImportMJCFSetup.cpp

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.

5ab6a0ad43 Fix issue with cone friction, we had to accumulate squared residual, not just residual. 
This fixes issue 1473, thanks to Avik De for reporting the issue.

88b49947b5 Composite of fixed code for mingw64(on windows) and general fixes for msvc. 
1) (win32window) don't convert char to wide, use char direct to window.
2) (CMakeLists) Don't link one library as static CPPLIB and no others (mismatched allocations)
3) (macros) Fix Gwen macros for mingw64 on windows build.  (changes are by compiler(msc_ver) not platform)
4) (FileUtils) sprintf_s reference by platform, not compiler (mingw64 support)
5) (b3OpenCLUtils) fix bad define name _MSVC_VER->_MSC_VER
6) (compoundCollision) remove unused variables, simplify operation.
7) (impulseconstraint) remove duplicated code block
