Hello! I have canceled the rewrite I was talking about in the previous update because I don't really have the time and motivation to work on it. So here are some improvements for this version
Update config system to ajUtils. (mostly just makes things easier for me to use)
Added debug option to config (instead of just putting debug stuff in the console all the time)
Fixed players being able to fly in-game if they were able to fly when they joined the game
Added maxplayers setting to arenas
Added maxplayer displays to signs and the join message (requires reset those messages)
Will clear a player's potion effects when joining a game to prevent things like speed and jump boost
This might be the last version of v1 because I am starting a rewrite. If any major bugs arise I will fix them, but probably no new features after this until the rewrite.
This update will probably also work on 1.11, 1.10, and 1.9, but I have not tested. It will definitely not work on 1.8. Tell me if you want 1.8 support and I might add it.
