* #1874 Introduce individual ConsoleLogger instance per class
- Create ConsoleLoggerFactory from which a separate logger can be created for each class
- Allows to support individual log level settings in the future
* Fix CodeStyle issue
* Replace full class name with import
* Update usages after merge from master
- FlatFile doesn't store the "realname" - all names are always in all-lowercase. Converting from flatfile to other data source should therefore not take over an auth's realname
- Adjust sample flatfile file to only have all-lowercase usernames
- 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
