Subject: plugins/muc/muc.lib: Improve set affiliation logic;

  - Each affiliation and role is now ranked
    - Changes up in affiliation will not downgrade your role
  - Now sends a new set of presences if you gained moderator in a semi-anonymous room.
  - Better input validation; matches closer with ':set_role'
  - Don't short circuit; as if user has non-default role they will not get updated
