Invalid json -- self-submission.json

[Paul-Nguyen]

redbox / config / src / main / config / home / form-configuration / self-submissionform.json contains invalid json due to strings with new lines (html code).

As new lines are control characters, and control characters are not valid string characters (see http://json.org/), the json should be appropriately stringified or better yet the html code should be moved outside of the json file.
