Optionally make a copy of the drawable's tiles in GimpDrawableModUndo 

instead of simply reffing drawable->tiles. Add boolean property "copy-tiles"
and a boolean parameter to gimp_image_undo_push_drawable_mod() to control
the new feature. However, pass FALSE in gimp_drawable_real_set_tiles() (which
currently is the undo's only user)
