Added 2 more authorizations:
rescue (name based): these players can ask the crew to rescue them onto the
ship.
signal (rank based): these players <if they are in the sailor guild!!!> may
signal for your ship to come to them.

Feel free to send in more ideas for auth slots.

P.S. You need to dock/resummon to see the new auth entries; you need to
quit/re-enter/reboot to be able to use the new sailor signal.
