JSON Pretty Printer for Serialized JSON

Json Pretty Printer for serialized JSON of the form: "foo": "{\"bar\"\"crow\"". Here the value will be displayed as a string by most pretty formatters but, in some cases (output from a Key Value store for instance) , we may want the value to be formatted. This is a small modification of the open-sourced JSON Formatter, and outside of this specific use, I would direct you to the original extension instead which is likely to be better maintained.

That said, feedback is always welcome.
