Subject: InitVars(): New MailList attributes:

    send_goodbye_msg: Says whether to send the goodbye_msg to members
    when they get unsubscribed.

    unsubscribe_policy: What is this list's policy on unsubscribes?
    (0 == unrestricted, 1 == admin approval)

    include_rfc2369_headers: Should the RFC 2369 headers be included
    in the messages?  Defaults to yes (and requires site admin
    complicity to disable).

DeleteMember(): New method which first checks unsubscribe_policy
before deleting the member address.

ApprovedDeleteMember(): Change userack default argument value to
None.  Also, when userack is None, default it to the value of
self.send_goodbye_msg.  Then of course, only send the unsubscribe ack
if userack is true.
