Title: Set reponse time header on responses

This is a really basic PR, which I've found quite useful for debugging while working on password resets.

Basically, it sets the header `X-Response-Time` on all responses, formatted like: `64ms`.

This is added to all requests processed by HexWeb.Router (so all requests on every router).
