Revamp the permissions propagation. This MAY mess up. Please test.
Change the slam bit from 3 to 4. Assume the old slam bit is always set. The new slam bit is a "changed owner" bit, correcting a bug where an item passed from the creator to another with less than full perms, then back (sale test) would arrive back full perm. Lots of in-code docs.
