New Rafiki Feature: Solved Feedback Gets a Reply When Resolved

Rafiki now closes the loop with you. When he solves feedback you've given, he will reply that it is fixed and live

For example here, @onealfa reported an issue with Rafiki Vote's display. Rafiki fixed it and then replied back to Onealfa that the fix is now live
