An ssiduous dockmaster who calls in the auto-ships

[Elysia]

You can now find an assiduous dockmaster at the rivership docks, who will call that river's autoship to that location.

The mob responds to saying 'help commands'. If the auto-ship in question is not occupied, it will hoist a flag to call in ships and reset the location of the auto-ship so it will arrive after the next tick.

I may be able to make this work for all ships, but given the potential for space problems, I'm rolling this out now and see if I can do the rest later.

Enjoy!

The Golden Tree, once the pride of Altara, now goes around the world collecting passengers. It's now an auto-ship. You can call it in at Illian and Tear. I'll add dockmasters at the other places in the near future, so you can do the same elsewhere.

Note: for now, it skips the "stop" between Illian and Tear, it skips Altara, it skips Falme and it doesn't go to Jafar or Tremalking. It was complicated enough at this point. I'm not sure how much more fits, but I'll tinker with that later, with the order of priority being Tremalking, Falme and Jafar. We'll see what fits.
