do not reject binary-only uploads that fail the "must be newer than" criterion

2008-12-09  Philipp Kern  <pkern@debian.org>

        * daklib/queue.py (cross_suite_version_check): add an additional
        parameter to specify if an upload is sourceful or not; do not reject
        uploads that do not satisfy the "must be newer than" criteria and
        are binary-only
        * daklib/queue.py (check_source_against_db, check_binary_against_db):
        invoke cross_suite_version_check as above
