At work we use roundup, and we have two users that need
to see "EVERYTHING" that happens on the issue tracker.
 Two solutions: 1) add a auditor that added their
usernames to the nosy list, 2) bcc a message to mailing
list

I liked #2 better because then the users could filter
the mailing list to a folder and still get nosy list
messages that where sent to the explictly in their Inbox.

This patch enables the bcc feature, so I just had to
add a roundup user for the mailing list, then figure
out what the user key was, then change
"nosyreaction.py" to: 


    for msgid in determineNewMessages(cl, nodeid,
oldvalues):
        try:
            cl.nosymessage(nodeid, msgid, oldvalues,
bcc=['20'])
        except roundupdb.MessageSendError, message:
            raise roundupdb.DetectorError, message

Where 20 was the key of mailing list user.
