When jumping overboard from a ship, I applied a whole ton of 'realism'
exemptions, so people who are water walking, floating, or of a flying race will
receive reduced/null damage.
When jumping overboard while mounted, your mount now comes with you.
When signaling a ship, the first mate and boatswain will now see tells from the
ship crew relating to signaling the ship.
The last mentioned change will require a dock+resummon with a 'quit real' in
order to take effect.
