Subject: Add CORS headers to backend responses

Access-Control-Allow-Origin:* header added to API responses to allow
angular to access API.

Note: This allows all domains to access this API through browser javascript

See <https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS> for a
description of CORS
