Simplifies if statements with && or ||

Removes one not existing argument in a JavaDoc
Removes some unnecessary variable assignments
Remove the check if an error happened while hashing the password in RegisterCommand.playerRegister because it's not possible that the hash is null
Fixes that the command use table isn't limited -> now again limited (Bug caused by my conversion to foreach)
More performance by using .computeIfPresent at GeolocationPart.addGeoloc(String)
