BedWars1058 WIP: Autoscale everything

Allow autoscale to be used on all serverTypes

Would also allow disabling of autoscale on bungee mode (which wasn't really possible before without making arenas not reset)

TODO:

[x] Pry autoscale out from being only multiarena
[x] Make BUNGEE_LEGACY be its own thing, not just BUNGEE but without autoscale
[x] Make the arena selector work with cloned arenas
[x] Make signs work with cloned arenas
[ ] Make join commands work (they seemingly already do but should probably be checked)
[x] Fix issue with arenas de-scaling even with players in them, making a broken game
- ~~There also seems to be an issue with worlds not being unloaded? Needs more investigation~~
- Turns out it was the private games addon. Mher is working on it
[ ] Probably other stuff that comes up during testing

Note to self: Dont forget to test with

[x] Internal adapter (MULTIARENA)
[ ] Internal adapter (SHARED)
[ ] Internal adapter (BUNGEE)
[ ] Internal adapter (BUNGEE_LEGACY)
[ ] SWM (MULTIARENA)
[ ] SWM (SHARED)
[ ] SWM (BUNGEE)
[ ] SWM (BUNGEE_LEGACY) And no me, don't be lazy and skip testing the bungee things, because I could have easily messed something up there on accident
