[pybullet] Add calculateMassMatrix.

acbe457d31 add option to statically link a plugin, select the postFix (to avoid naming conflict of multiple plugins functions ('initPlugin' becomes initPlugin_postFix) 
pass events (keyboard, mouse, vr controllers etc) to the plugin, and clear them after the tick callback, so that it doesn't interfere with Python 'getEvents'

ee30ca93c5 [sharedmemory] Fill-out calculateJacobian command. 
The server command processor actually didn't do anything with
the local point that was passed along with the calculateJacobian
command. Added in the necessary bit of math to return the
corresponding jacobian.

Also, fixed a typo in pybullet that was returning the same
jacobian for translation and rotation.

c2ca88bf44 added b3PhysicsParamSetInternalSimFlags command, and pybullet setInternalSimFlags API. 
//Use at own risk: magic things may or my not happen when calling this API.

This allows to enable/disable robot assets (samurai world, gripper, KUKA robot etc) in Physics Server (and App_PhysicsServerVR etc)
1 = create robot assets
2 = create experimental box-vr-gui

Add optional command-line parameter for App_PhysicsServerVR, --norobotassets, to start with an empty world, no assets in VR (no gripper, no kuka)
