Configuration Rewrite

[trainb0y]

The current configuration system is... really dumb.

It uses the built-in bukkit api, which is really terrible compared to libraries such as configurate and kx.ser
In addition, effects such as projectiles, and maybe multiblock actions, should be able to be defined in config files.

If simple config files aren't enough, I wouldn't mind messing around with using kotlin scripts loaded at runtime (kotlin supports it pretty well, and performance should be good enough:tm:)

Gone in favor of having no configuration altogether (temporarily)
