jpbouza Feature Request: Transformation Constraint now allows applies rotation
offsets too (like for location)

This is useful in some cases when Copy Rotation constraints would otherwise be
used for this purpose but cannot be used for various reasons. Basically, this
works in practically the same way that the Copy Rotation offsets work, including
the same weirdness that you'll get when trying to manually rotate these in the
3D viewport using "global" space manipulations ("local/normal" spaces though
still seem to work really nicely).

WARNING: this may potentially break old files with transform constraint setups
involving rotation outputs. Please check whether this causes any problems on old
files, and report back if there are any issues.
