Add a confirmation page

Generally I prefer confirmation pages to the flash message thing
(they’re harder to miss). So this commit adds one.

It also adds some logic to this page, so that, depending what the user
has told us about the thing they’ve submitted, we can tell them how
quickly to expect a response.
