Command: harbour/harbours - lists harbours and lets you jump there

Description:
	Lists all registered harbours/ports/jetties with their full
	filename, their short descriptions and the corresponding numbers.

	Use the corresponding number as argument to jump there.

Syntax:
	harbour
	harbours
	harbour <number>
	harbours <number>

Examples:
	harbour
	harbour 10

Note:
	The numbering of the harbours is permanent. Only in rare occasions
	they might change.

	If no short description is shown, the room is not loaded at the
	moment.

	In former times there were two commands: 'harbours' to list them
	and 'harbour <number>' to jump there. This changed with the new
	management of the ships.

	This command is a bit like those commands for lazy wizards as
	listed in See also: below. But there is no easy way to find all
	harbours.

	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.
