develop-2.0 responseMessages data not rendered in UI

[billdami]

I know I had brought this up in another un-related issue, but figured it might be better to just open a new issue for it instead of using the old one for status tracking purposes.

I just downloaded the latest version of the develop-2.0 branch and it looks like the api operation response messages data is still not being rendered in the UI, for my own API or for the demo petstore API, even though it is using the new "responseMessages" key name instead of errorResponses which was deprecated.

This should be addressed now.
