Minor:
- Added missing types as a comment to the 'cloudsystem-extra' config
- Added a warning when saving world files and something is wrong with the main world. By that no errors shouldn't occur anymore if the plugin tries to teleport the players in that world to the main world.
Fixed bugs:
- Fixed something that breaked compatibly to a plugin in the past
- Fixed that the CloudNet signs didn't update on init (if enabled)
- Fixed that achievements didn't got saved if SQL was enabled
Probably did some more what I just forgot.
