Arenas Inactivity Should be a 30minute timeout

@Martian00 Arenas and the ltm (but most likely permanent) control mode should have an auto fill, that way if someone ditched or goes afk you can have another sub in. This could work like selecting duos or trios in the apex games, except you would select play or fill. If a player does not move by their own accord for an entire round, it should kick them. There should not be a 30 minute penalty for going afk tho, only a 10 minute one should serve as a sufficient deterrent.
