Added support for AdvancedSlimePaper in dynamic arena runtime worlds. Setup/editing worlds remain regular worlds so arena templates can be edited and saved universally across supported servers.
Added void safety so players falling below the arena during the finish phase are rescued to a safe location from the last played game.
Removed the hard 64 player limit from arena minimum and maximum player settings.
Arena minimum players can now be set to 0 to make an arena admin managed.
Dynamic arena worlds are now unloaded and deleted before server stop.
Fixed shared spawn points being reported as not enough spawns.
Fixed unfinished dynamic arena setups being reopenable even when the lobby or game template has not been saved yet.
