ADDED:
- Added a message when using the kits command, and they're disabled, stating they're disabled for the game.
- Added a spectator GUI (spectators can click player heads to TP to them)
[This has not been tested much as I didn't have players to test with. Please report any errors found]
- Added most sign lines to the language.yml allowing you to customize your signs
- Added the status messages to the language.yml allowing you to customize status message
- Added the ability to add multiple potion effects to one potion (separate by a semi-colon - See Items WIKI)

CHANGED:
- Now when kits are removed, the kits message will not appear upon joining the game
- A lot of internal changes on how command classes handle fields/static getters.
- Changed error messages when item stacks are broken in config

FIXED:
- Fixed an issue where deleting all kits would cause some console errors
