modedit: Store single copy of the footprint in undo 

When changing elements in the module editor, each element shares the
same parent.  Undo commits store a copy of the parent as it existed
before the change.  For footprints with many elements, this creates
large, slow undo commits as a copy of the full footprint is stored for
each element being edited.

This keeps a single copy of the footprint in the undo stack per edit.
