[IMP] auth_signup: various usability improvements in signup process

 * allow new signup on invalid token
 * relabel signup buttons
 * send a welcome email upon signup with a signup token.

This way, should the token somehow be usurped by someone else,
the original partner's email address will be notified.
(before the usurper can change the email)
