Redesign Feedback Form dialog

[waderyan]

To resolve issue #2662 we're going to redesign the form to eliminate the input box. This makes sense because we are using twitter now.

@bgashler1 hoping to get your help on this.

This feature request will not be considered in the next 6-12 months roadmap and as such will be closed to keep the number of issues we have to maintain actionable. Thanks for understanding and happy coding!
