3431773800 expose btMultiBodyConstraint applied impulse (force) on its degree of freedom(s), 
only tested for btMultiBodyJointMotor for now.
See also MultiBody/MultiBodyConstraintFeedback example

89edc40d61 First step in btMultiBody joint force/torque feedback. There is still some work to be done for 'mobilizer limit/motor'. 
See examples/MultiBody/TestJointTorqueSetup and examples/Constraints/TestHingeTorque for joint feedback.

f02dd51597 Added a first version of a Featherstone multi body implementation. 
The original version was written by Stephen Thompson.
I replaced Eigen math by Bullet LinearMath, and added a dedicated 6x6 matrix solver. 
Also I integrated support for collisions/contact constraints between btMultiBody and btRigidBody, and de-activation support.
See Demos/FeatherstoneMultiBodyDemo/Win32FeatherstoneMultiBodyDemo.cpp for example usage.
There is currently only support for contact constraints for btMultiBody. 
Next on the list will be adding support for joint limit constraint for btMultiBody. 
The implementation is still experimental/untested, the quality will improve in upcoming Bullet releases.
