Fix gizmo should use inverse/reverse transform when specifically manipulating child offset frame of a joint #775

OpenSim idiosyncrasy means that the position/rotation of the offset frame isn't where the child ultimately ends up because the joint places a constraint on the child and the offset is treated as a downstream thing.

Partially fixed for translation, but rotation remains elusive ;)
