Two transform tweaks:

* [Peach Request] AutoIK now respects axis locking (rotation locks).
- Temporary DOF-Locks are turned on for those bones that are part of an AutoIK chain while transforming. These locks get cleared after transforming.
- This works for all bones except the root bone of the chain, which doesn't seem to be able to be locked.

* Limit Location constraint can now optionally affect Translations too (i.e. NKEY panel values won't change). 
- LimitRot,LimitScale support (for their respective transforms) will be done at a later date
- This only works if the constraint is using World/Local space (the other spaces are not supported yet).
- I've added a temporary button in the LimitLoc panel to enable this option (it is disabled by default). This button will be properly assigned a place in that panel sometime.
