fixed SCRIPT_NAME in ZRoundup for instances not at top level of Zope (thanks dman) fixed some sorting issues that were breaking some unit tests under py2.2 mailgw test output dir was confusing the init test (but only on 2.2 *shrug*) fixed bug in the init unit test that meant only the bsddb test ran if it could (it clobbered the anydbm test)
