Remove REST transform influence in skeleton bones

Browse Source 
* Animations and Skeletons are now pose-only.
* Rest transform is kept as reference (when it exists) and for IK
* Improves 3D model compatibility (non uniform transforms will properly work, as well as all animations coming from Autodesk products).
