Switched to using HikariCP as database pool.
The previous database implementation was not properly synchronized and could read / write wrong data from / to the database.
Performance should also be better now.
The database will now NOT be automatically created, this has to be done manually!
As this update made deep changes to the configuration, they should be regenerated!
This update also includes a permissions fix: A player without onlinetime.see.other was able to see if a player has not yet played on the network.
