Bugfixes for Transform (related to Constraints):
* Reverting a previous commit where I wrongly assumed that the code was not doing things the right way. This makes a few cases work better normally again.
* Object-level Transforms should now perform normally again. Now, transforms are only get inverse-corrected for constraints if certain constraints are the first 'active' constraint.
* PoseBone-level Transforms still need to be fixed, although I might have done a few tweaks here.
