Email attachments

David sent me a two examples:

One was pilot error (forgot to attach the file(s) after writing up the
email message).  The other one was attached, but the .ksh file
extension confounded mailman (Python, actually) so the results weren't
pretty.

Mailman is not particularly kind to attachments, but I changed the
configuration to tolerate them a bit better as suggested here [1]:

SCRUBBER_DONT_USE_ATTACHMENT_FILENAME = False
SCRUBBER_USE_ATTACHMENT_FILENAME_EXTENSION = True

If this helps, good.  If not, we can take them back out.
