Re: [webpayments] Should we expose status change events in the browser API? (#41)

This will likely be influenced by the proposal from @rsolomakhin actioned here: https://github.com/WICG/paymentrequest/issues/28

There seems to be an implied requirement for the payment app to be able to communicate with the calling application (website) prior to the former returning the payment response.

Right now this is being accomplished through events in the paymentRequest spec and through HTTP callbacks in the CG proposal. 

We should consider if there are use case(s) that justify this requirement first and then, if we feel these exist, decide what the mechanism will be for facilitating this.
