* feat(feedback): convert to react and redux
- For styles, remove "aui-dialog2" nesting so existing styles
can be reused.
- Remove Feedback.js and replace with calls to redux for state
storing and accessing.
- Add dispatching to FeedbackButton instead of relying on jquery
clicking handling so the button can be hooked into redux.
* address feedback
* remove calling to not show feedback for recorder and filmstrip
