* 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* Cleanup: remove outdated warning for session timeout = 0
- Remove outdated warning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
- 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
- /email recovery generates recovery code and resets password only if recovery code is also given
- Change data source method to return email and recovery code
- Drop initialization of all columns on table create in favor of checking each column individually. This is slower but guarantees that each column is only defined once in the code. Columns are only created once so having clean code outweighs performance.
- Write more datasource integration tests
- 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
- Change ForceFlatToSqlite converter to use a generic datasource destination (i.e. can be used for Flat2MySQL later)
- Add tests, including for FlatFile
- Check that user is not present in destination datasource before adding
- Persist last location from flatfile as well
