issue #1069: Add 'raw' link to swagger ui so that the raw swagger json can easily be retrieved

This adds a link to the Swagger API docs to an application's detail view in
  the **Applications** tab of the web interface. The link produces the Swagger
  JSON directly. If authentication is turned on, the link requires authentication,
  too.
