First commit, for test, for using Library files for synchronizing partial
data. This functionality is going to be in Outliner, for now only use
for testing while consulting me. :)

Usage: New option in SHIFT+F1 append window, "Sync Pose". When pressed, you
can append/load an *Object* of type Armature, this then replaces its
Armature and Pose with the selected Objects. After that it deletes the
appended object.

Note: it currently appends also Objects when used in Pose Constraints...
