Hinge Bone Transform

Browse Source 
====================

This changes the way hinge bones are transformed when their parent bones
are also selected. Before it just disabled transform for these, now they
are rotated and scaled as well, but without influencing the transform
center, which gives behaviour as if they were regular bones.
