Command: ship/ships - lists ships and lets you jump there

Description:
	Lists all active ships with their full filename (the room, where
	you enter them), their short descriptions and the corresponding
	numbers.

	Use the corresponding number as argument to jump there.

Syntax:
	ship
	ships
	ship <number>
	ships <number>

Examples:
	ship
	ship 10

Note:
	These numbers might change if a ship checks out and checks in later
	again after another ship checked in meanwhile. They are NOT fixed!

	The 'ship' command was introduced with the new management of the
	ships on Feb 9th 2016.

	'ships' (plural) is for compatibility to 'harbours' vs. 'harbour'.

	This command is a bit like those commands for lazy wizards as
	listed in See also: below. It is a shortcut for something like
	'goto /lib/ships/<ship>/bridge' and run around and look for the
	enter room of the ship.

	Wastl ('whois wastl' or https://nemesis.de/lpc/bin/finger/wastl )
	and Kiri ('whois kiri' or https://nemesis.de/lpc/bin/finger/kiri )
	developed the new management of the ships in February 2016. Wastl
	coded it.

	The former management of the ships was developed and coded by Junky
	('whois junky' or https://nemesis.de/lpc/bin/finger/junky ) in the
	1990s.
