* primary - user who is authenticated, owns address, valid cert.
* primary - user who is authenticated, owns address, but invalid cert.
* primary - user who is authenticated, but does not own address.

Required email feels more "correct", still some work to do though for working with expired certs cleanly.

* Changed the state machine so pushing a state to the stack is optional.
* Changed the verify_primary_user screen to have an optional cancel button
* Updated required_email to handle primary verification of unauthenticated users.

It is now possible to sign in to BrowserID using a primary email even if the user is not authenticated to BrowserID.  Needs a lot of cleanup.

* Defer off to "primary_user" screen and let that take care of the rest.
