Support JSON in body field

[jstockdi]

Any thoughts on supporting JSON in the body field? In order to escape JSON into a one-line string, I'd keep a "my-http-types.json" and then covert it into http-types.json in order to use.

ie:
In addition to:

"response": {
    "statusCode": 200,
    "body": " { \"field\": \"value\" }",
    "headers": {
      "content-type": "application/json"
    }
  }

Support:

"response": {
    "statusCode": 200,
    "body":  { "field": "value" },
    "headers": {
      "content-type": "application/json"
    }
  }
