forked from bartvdbraak/blender
- rewrote arm rig so it creates 2 chains and blend them automatically (like the leg)
- use reverse order for palm fingers (pointer first) - allow copying bone class instances to exclude some bones - doc generation had a python error (incedently updated online docs linked from the splash)
