Fixed a problem where members of a deleted mailing list were hanging around.

This would cause duplicate members (e.g. owners) if you created, deleted and
then recreated the mailing list.

Mailman.app.create -> Mailman.app.lifecycle; Mailman/doc/create.txt ->
Mailman/doc/lifecycle.txt; also added a remove_list() function.

Added SubscriptionError base class, made HostileSubscriptionError inherit from
that, and added a new AlreadySubscribedError.

Rewrote bin/rmlist to use the new lifecycle.remove_list() function.

IAddress.subscribe() must now throw an AlreadySubscribedError if the address
is already subscribed to the mailing list with the given role.

Added a Subscribers roster, attached to the IMailingList which gives access to
all subscribers of a mailing list, regardless of their role.  Added a new test
for this roster.
