[Bf-python] Python -- Orientatoin problems.

[Ken Hughes]

I think I found the problem for bug #2230, but can't think clearly enough
to find a solution (if someone can read the armature code, please explain!).

Looks like getRestMatrix() is relying on the bone's roll variable to calculate
the rotation, but roll is always 0.  In most of the armature code I've read
seems they calculate roll then reset to 0; can't see where it's being used.
I put a printf in make_boneMatrixvr() -- called by Bone_getRestMatrix() --
to print roll and it's always zero.
