        - fixed printer policy handle leak in the allow MS printer wizard
          stuff.
        - mimic behaviour of NT on open_printer_ex() calls by not allowing
          call to succeed if connecting user doesn't have at least print
          permissions to the printer.  Unfortunately, this seems to trigger
          a anonymous connection re-using bug so subsequent connects to the
          printer by a different user from the same machine always fail.
          Blame Tim. =^)
