Subject: [PATCH] Fix problem with concurrent posts as reported in #813 by
 preventing accidentally submitting a post twice (with Javascript) and
 modifying the move-old-files-to-archive code to not move the files away if
 they belong to the same submission as the one we're accepting (this mitigates
 a concurrent post to at least not end up with a non-existing draft).  -
