Added ability to customize all messages.

Added tab completion for sub commands.

Added new stuff to config.

Added ability to save interval on restart.

Added ban reasons.

Added a few stats: How many people were ever banned, how many people were banned last banwave.

Note: I would recommend deleting your old config to get new features.

In this update I have added a few config changes and made it so you can add/remove offline players to the BanWave if they have joined the server before. I would recommend resetting your config if you want the new features.
