Proposal: Promise.prototype.Finally

I created the following gist as a proposal for the addition of a `finally` method to the prototype of the Promise constructor, either for ES6 (if such a thing is considered valuable and could be fast tracked at this date), or for ES7. This method would take in a single callback that would be
