* Introduce hasSession field in datasource
That makes isLogged more consistent as it will be '1' only when the player is online.
* Fixes
* Fix unit testing
* Update config doc
* Create SessionService
* Create test for SessionService, avoid DB operations if sessions are disabled
* Cleanup: remove outdated warning for session timeout = 0
- Remove outdated warning
- Encapsulate session enabled check in SessionService
* Fix failing SessionServiceTest, add data source integration tests for session methods
- Delete LimboCache and LimboPlayerStorage: LimboService now handles all LimboPlayer actions
- Revoke player rights when creating a LimboPlayer, within the LimboService
- Various fixes and improvements
- Introduce new LimboService with a higher level abstraction for outside classes to trigger LimboPlayer actions
- Add methods to LimboPlayerTaskManager for muting the MessagesTask safely
- 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.
- authme.cache to authme.data
- Rename PlayerData to LimboPlayer to match with LimboCache
- Move authme.converter to authme.datasource.converter
- Split output package into output and message
* the methods inside it renamed to fit with class name
* cache folder changed into playerdata
- Renamed LimboPlayer to PlayerData
- Added fly speed to PlayerData
- Removed player's name from PlayerData object
- Added getPlayerLocationOrSpawn method in spawn loader.
- New injector method allows to retrieve services if they've already been instantiated -> useful for onDisable() which might be run after aborted initialization
- Deprecate various methods that need to be removed
- Adjust javadoc
- Remove unused PlayerAuth constructor
- Replace legacy Settings with NewSetting calls
- Add process service to all (a)sync processes
- Change IP manager to only cache the calls to the VeryGames API
- Abstract Messages into two layers: the top layer 'Messages' is how Messages can be retrieved and sent as before. In the background, package-private, MessagesManager actually does the file read and worries about I/O while Messages takes care of higher-level things (such as joining two lines or checking the current language).
