== Pose Mode - Copy Menu (Ctrl C) ==

This now works even when there is a proxy-protected bone selected with a few differences.
* The Transform Locks, IK-Flags, and Custom Bone Shape settings are unavailable, as they would be reset by the proxy protection anyway

Also, the Copy Constraints options have been altered so that they do NOT free all existing constraints on the target bones before copying.
* Constraints are now appended to the end of the constraint stacks, with those added to bones belonging on proxy protected layers getting tagged as 'local' constraints.
* This is more useful for riggers than the previous behaviour (which was quite nasty too).
