Audit Mode Formatter Integration

Right now I only have the STDOUT formatter tied into the event bus.  I'm going to add the JSON formatter and update this review, but I wanted to get it started.
I actually don't know.  The parent class' `initialize` method requires an argument, and this has been working.  @danielsdeleo @lamont-granquist Do you know if a call to super automatically passes the arguments?
