Hacked in pretty JSON option
Hacked in pretty JSON option

Just need to include `?pretty=true` to a request and the JSON returned will be formatted. As I was digging in there I think I may consolidate all of the Display logic into a single class and potentially bring back `.json` and `.xml` extensions to dictate what is returned. Would help a ton in scenarios where I have an endpoint that I want to server up a template on error or return JSON on success.
