Using another way to cache to prevent problems, even if two clients from the same ip address were connected, but there is still a problem which may never can be resolved:
Problems with servers where the extension is installed also another ts client is running, which causes that the names of both ts clients are switched when another user gets a pm from one of both clients, if the client to which the pm was sended rejoins
Fixed language mistakes
Fixed that the command !auth was still used even if an alternative authenticator like UltimateTs Authenticator was registered
Improved performance massively, by caching the username
Fixed that if redisbungee was used the auth message was send multiple times (to fix that you need to disable on all except one bungeecord "RedisBungee.MainServer")
