New: Write Protection for transform values.

You now can set, in NKEY Transform Properties Panel, per XYZ rot/loc/size,
a protection for Transform tools to not change these values anymore.
This now works for Objects or for Bones in PoseMode.

Usage is especially for character animation, to give Bones in a Pose
defaults for rotation axes, so you don't have to worry about the correct
limitations (or setup complex IK limits).
Of course, this feature doesn't influence the animation system.

As an extra also the Transform Widgets then draw less handles. Note this
is based on the actual locked value, and depends still on Manipulator
orientation whether it can be used really.

Implementation warning: I had to remove the 'return' in the middle of the
editobject.c compatible_eul() call. It now makes nice compatible eulers
when they're simple (single axis rotations). Unfortunately there was no
note in the code why it was ever removed...

ALso: fix for crash in using Crease Transform and Mirror modifier.
