Johannes Brust fa1d1fc8ee 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

(cherry picked from commit 5795bd676f)
