Three bugfixes from tracker;

- Nurbs objects didnt render ray-transp. Was caused by 1) wrong normal calc
  and 2) quads with vertices on same locations. Solved it with nice code that
  checks illegal quads and turns them into triangles
- Made 'physics engine' variable SUMO default
- Typo in toolbox fix; cyclic isn't F but C
