Pose Lib: Start of PoseLib UI in Armature buttons

This presents a UI from which PoseLibs can be assigned/removed from
Objects. From here, it is also possible to see the list of poses and
add/remove poses from this list.

Known Issues:
- [Py/RNA/Operators BUG ALERT!] If after immediately starting Blender
you try to remove a pose from the PoseLib using the UI buttons, you'll
get a an error the first time you do so (but not for subsequent
attempts). This seems to be caused by the "pose" enum (dynamically
generated) of the POSELIB_OT_pose_remove operator, which does not seem
to be getting initialised when the operator's exec gets called without
the invoke having been called previously
- Changing the active Pose Library still seems to be broken (to be
fixed soon)

Todos:
- Operator button to make the selected pose get shown in the 3d view
- Restore the "validate action" operator and add that to this panel
- Rename pose access
