- Create class to handle the creation of "LimboPlayer tasks" (adds encapsulation, reduces duplication)
- Move group setting into its own class because (mutual dependency between LimboCache and PermissionsManager otherwise)
- 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
- Make /authme unregister behave the same way as /unregister for optional registration: user is informed but can continue playing; no teleportation to spawn
- Rename *taskId methods to *task to reflect what they handle
- Remove usages of Wrapper where applicable
- Replace some uses of legacy Settings with NewSetting calls
- Create IP address manager for handling and caching IP addresses -> outside of the manager I do not want to care about caching details
- Make more processes use the ProcessService in favor of statically injected objects
- Rename HashResult to EncryptedPassword to reflect its broader use
- Use EncryptedPassword in methods that require the hash and the salt, instead of passing them as strings separately
- Store EncryptedPassword as field in PlayerAuth; updatePassword() thus processes the entire data in the EncryptedPassword object
- For encryption methods with a separate salt, the hash is useless without the salt, so hash and salt should always be persisted and retrieved together
- 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).
