- Overloaded method with (String, String...) as args was problematic as it could be confusing on its own and also confusing with the (CommandSender, String...) flavor
- Couple AuthGroupHandler closer to the LimboService: whenever a limbo player is restored, the auth group should be restored as well. This fixes some consistency issues.
- Move AuthGroupHandler into limbo package and make it package-private
- Change permission handler to skip any empty groups (prevents odd command output e.g. for BukkitPermissions)
- AsynchronousLogin: call common permission methods through CommonService instead of PermissionsManager
- CommandManager: remove superfluous replacement of %p (handled by lazy tag replacer)
- Remove unused method in CommonService
- Create DebugSectionConsistencyTest
- SendMailSSL: Enable debug output if AuthMe log level is set to debug
- Add Utils#logAndSendMessage and replace existing, separate implementations
- Improve how a player is being switched between permission groups (add new group before removing old one)
- Remove group handling logic from LimboCache: AuthGroupHandler is now solely responsible for changing the player's permission group
- Replace CommandService and ProcessService with CommonService: a service that offers our typical needs to work with settings, messages and permissions
- Remove validation methods from CommonService: inject ValidationService directly. Validation methods are not used very frequently and therefore don't belong in CommonService. Their presence was a relict from our architecture before injection was used.
