Audit Mode Formatter Integration

@mcquin 

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.
So, like RSpec in that you have:

```ruby
describe "SomeClass" do
  describe "method in SomeClass" do
    # tests
  end
end
```
I can waffle on this... On one hand, I am not a fan of having singular and plural method names/keywords/whathaveyous. On the other hand, in the context of a recipe I think it makes sense to have two different terms: one to denote "OK, recipe, this is audit stuff now", and one to denote "Verify this, yo." Sort of like a resource/provider and resource/provider methods relationship.
