Apply and heavily modify patch from remyDev which adds "lock position" to GimpItem, similar to "lock content". Lock position disables all sorts of translation and transform, from the GUI and the PDB. Cleaned up some aspects of the lock content code as well because a second instance of similar code always shows what went wrong the first time.
