The bots make room for a person who joins, and the server browser's
listing counted their slots as free, but the LAN advertisement and the
join's check still asked for a free slot: with 15 bots and the host a
lobby of 16 was advertised closed, and a Quest on the LAN was refused
("attempted to join a closed game"). Both now count a bot's slot in a
lobby as a person's, as the listing does (network_game_server_room_for_person).
