Hi, here it is - seems to be working properly.

There's still a few uses of PROP_ANGLE rna properties (which convert into PROP_UNIT_ROTATION) which I haven't checked out yet, such as the limit rotation constraint, pose channel ik_min and ik_max, and brush texture angle. For the brush angle, it probably needs to be converted to use radians internally, not sure about the constraints.

Anyway those extra conversions are pretty easy to do later, but for now you can evaluate the patch.

thanks!
