Title: WIP: Issue 182 sign in messages

This is based off of #526 and should not be merged until after that.

One item I am still wondering about is whether emails should always be prefilled, if we can guess it, or whether we should pre-fill email addresses a single time when the user changes from the /signin to /signup pages (or in reverse).
