Rename some things for better clarity
[bug 1030526] Add cors; add api feedback get view

* add cors headers to current api views
* add /api/v1/feedback/ GET view which is kind of like the existing
  front page dashboard json formatted output view, but better
* add required tests
* move some things around to support all that
