delete_orphan_files.php [options]
Deletes all files and their File entries where there is no link to a
Notice entry. Good for cleaning up after user deletion or so where the
attached files weren't removed as well.

  -y --yes      do not wait for confirmation

Will print '.' for each deleted File entry and 'x' if it also had a locally stored file.

WARNING WARNING WARNING, this will also delete Qvitter files such as background etc. since
they are not linked to notices (yet anyway).
