!dungeon join: shows a modal window with a list of all the dungeons. When the player selects a dungeon, he receives a message if the queue was successful or not (if his vocation can't take part in that dungeon, for example).
!dungeon random: the player is automatically queued on all dungeons his vocation can take part in.
!dungeon leave: the player leaves the queues he had previously been in.

What you can configure:
- name: The dungeon name that appears in messages and in the !dungeon join window
- team: what the dungeon team should consist off, e.g: PALADIN + SORCERER + DRUID + KNIGHT
- entrance: the position INSIDE the dungeon the players will be teleported to when a team is found
- time: maximum time (in minutes) the players have to finish the dungeon, otherwise no loot is awarded
- spawns: table containing all the monsters that should spawn, each entry should look like this:
	-- for a normal monster:
		{name = 'Rat', position = Position(142, 381, 7), time = 10, boss = false},
	-- for a boss monster (spawns when all normal monsters are dead):
		{name = 'Cave Rat', position = Position(142, 381, 7), time = 0, boss = true},
