Fairly significant change to the way member and nonmember moderation occurs.

Now, nonmembers are represented by a separate roster of IMembers, the latter
which has grown a `moderation_action` enum.  When that action is `defer`, then
the normal processing rules apply.  Anything else and the `moderation` chain
is jumped to for a shortcut to moderation (which may include immediate
acceptance).

TODO: handle unregistered nonmembers.

Details:

 * The member-moderation rule is renamed to just moderation, and handles both
   members and nonmembers (though the latter must currently be registered).
 * The moderation rule is moved up in the builtin chain.  It is now checked
   after `approved`, `emergency`, and `loop`, but before the normal moderation
   checks.  This means that nonmember postings will be (by default) held much
   earlier.
 * IMember.is_moderated is removed.
 * IMember.moderation_action is added.
 * IMailingList.default_member_moderation is removed.
 * IMailingList.default_member_action and
   IMailingList.default_nonmember_action are added.
 * MemberRole.nonmember is added.
