Temporary Solution to the boat death problem

[baalzy]

Wasn't sure if I should put this in bugs or not, I figured server would be safer.

We all know about the falling problem w/ boats and the easiest way to avoid that is to have levitation, but not everybody is capable of levitating themselves.

If it wouldn't take too much time I think it would be cool if the devs could put NPCs at the docks which hand out summoned levi rings when hailed.

Doesn't give anything permanent but provides 30ish minutes of free levitate to people who are traveling to/from Kunark via boat.
