A cleaner that merges before it deletes, and maintenance mode

Stacks of the same item lying near each other become one — most servers go from twelve hundred entities to four hundred and nobody loses a thing. Only if that was not enough does a countdown start and anything get removed: items, experience and spent arrows by default, never mobs, with named and tamed animals and anything the game refuses to despawn protected. A server with nothing to clean is never counted down at, and one command says what a sweep would take before you trust it. Maintenance mode closes the server with a reason, and tells whoever tries to join the same thing in the same words.
