cosmetic fixes for do_accept and do_accept_stableupdate

2008-08-31  Philipp Kern  <pkern@debian.org>

        * dak/process_new.py (_accept): new helper function to accept
        an upload regularly, obeying no-action if set
        * dak/process_new.py (do_accept): use _accept
        * dak/process_new.py (do_accept_stableupdate): bail out in else
        on binary uploads, in case we missed something; use the _accept
        helper; reordered the queue checks to do frequent cases first
