I haven't made 100% of the messages configurable yet, but this new version includes a complete moderation history against a user.

While I was at it I also did a few other things like:
changed duplicate messages (broadcasts and chat) to broadcasts and action bar messages.
Restructured how auto-unmoderating a user works
Fixed some of the wrong messages being sent
Changed mutes and jails to now only count down if the player is online.
