Changes to honor SMTP_MAX_RCPTS again. Specifically,

deliver(): Does the actual job of delivering to a list of recipients.
Takes the mailing list object, the message, and the list of recipients
and returns a dictionary mapping refused/failed addresses to a 2-tuple
containing the error code and the error message.  This function also
logs chunk delivery time -- the delivery time of the entire message
isn't recorded any longer.

chunkify(): Turn a list of recipient addresses into a list of lists,
where each sublist is no larger than SMTP_MAX_RCPTS in length.  A
minimal amount of sorting is performed: addresses are collated on the
top-level domain (i.e. `.com', `.net', etc.), but each chunk is filled
completely.  This should balance the ability to give the MTA a chance
to do more detailed delivery sorting with the amount of work being
done in this module.

process(): Changed logic to use chunkifying algorithm.  If
SMTP_MAX_RCPTS is <= 0, no chunking is done.  While we do still log
the recipients that fail, we don't know whether they all failed or
not.  If any temporary failures occurred, raise SomeRecipientsFailed.
