Is it possible to have a message when you reach a specific level.
Messages:
        value: true
        # Message sent when reaching level 10
        level: 10
        message: "New Jobs are abailable"

This would be very useful for what I have planned.
I wish to have a jobs level tree, where when you reach a specific level in a job, new jobs open up, either higher paying ones,
or new entire job classes.
