Rework save format and punishment manager

- Punishments are now saved as JSON in files named after their targets
- Each punishment type now has its own Java class
- Each file contains a list of JSON objects that is updated every time something changes (e.g. player muted, banned or unbanned)
- Punishments have a unique ID now; if something changes, the new version is added to the list and overwrites the old version
- 'Undo' has been renamed to 'cancel'
- You can no longer mute or ban players if they are already muted or banned
