Multithread GraspitServer

Added arrows to the guides so that the use can see which direction they
turn in.
make fingertips rubber to generate more candidate grasps.
Made egPlanner mutex recursive.
Changed text width of handview because some text was forcing the window
size to change.
Change the transparency of the reference hand
Modified the way that bodies are cloned so that any groups that store
geometry are replaced instead of being copied. This allows the material
nodes to be set correctly for clones in situations that previously did
not work correctly.
