Implemented using a batch-wise dependency-scanner in delayed (snappea) style. * no tests yet. * no real point-of-entry in the (regular, non-admin) UI yet. * no hiding of Issues which are delete-in-progress from the UI * file storage not yet cleaned up * project issue counts not yet updated * dangling tag values: no cleanup mechanism yet. See #50
