Fix bug in server handling of inverse dynamics
...
The current implementation of processInverseDynamicsCommand has two issues:
1. For floating bases, the handler is not properly copying over the position and orientation from the client inputs.
2. For floating bases, the handler is ignoring the position of the joint angles from the client inputs.
This CL fixes both issues. While the fix for (2) is straightforward, I am not sure whether or not the right pybullet API convention is to have (x, y, z, orn) passed in, or instead (orn, x, y, z). The former makes more sense to me and is what I implemented.

Add deformable contact forces info
...
- add contact information for collisions between rigid and soft bodies
- collisions between different soft bodies are not supported
- uses impulse acting on tetrahedral nodes for calculation of forces
- contact points are approximated by node positions
- multiple forces acting on identical nodes are accumulated
