Re: [w3c/push-api] Fire pushsubscriptionchange when user revokes permission (#116)

+ 1 For triggering a callback when subscription is revoked by the user

This would allow the server to know that a user (for example a user id associated to that endpoint) is no more reachable with push notifications **before** trying to send them. This allows better handling for providing fallbacks methods (e.g. email). Beside that it allows to determine **when** a user has unsubscribed and do some analytics. I wrote more extensively about this topic in [this blog post](http://blog.pushpad.xyz/2016/05/the-push-api-and-its-wild-unsubscription-mechanism/).
