Various neglectable changes while looking at recent commits
- Remove Inject annotation on ProtocolLib adapters that are no longer created via injection
- Reduce ProtocolLib adapters to package private - interaction always goes via ProtocolLibService
- Fix typos
- Teleport player to spawn immediately on PlayerLoginEvent.
- Only save authenticated player's location on quit.
- Fix player's last location get reset if fail to login.
- Change permission handler to retrieve the services it needs, instead of getting them from the PermissionsManager
- Reduce visibility of some methods
- Add Reloadable interface
- OfflinePlayer objects were never mapped to names
- Essentials purge was run even if setting was disabled
- Console user saw messages twice
- Misc: trivial field reorderings, change DefaultPermission to be null safe
- Permissions: do not expose PermissionHandler just to get its type
- Test runner supporting new "DelayedInjection" annotation: such fields are only initialized with instantiation right before the first time they're used in tests, allowing to set up mock behavior beforehand
- Rename autoPurging to isPurging: we should always register if a purge task is in progress (regardless if autopurge or not) and deny any new requests
- Reduce the same logic being coded multiple times by calling through the methods
- DataSource: remove purgeBanned in favor of purgeRecords, both do exactly the same thing
- Remove various imports / unused fields
- Make CacheDataSource call source for purging on DB
- Minor: SQLite - place creation of PreparedStatement outside of loop
- Make specific purge actions called from task package-private (clearer from the outside which methods can be called from the outside)
