* Validates the sent login form and creates a session.

* a) require refactoring code similarities in both p_confirm and p_alter branches
* b) require some way (e.g. an Exception) to signal back to doLoginForm() that
* the token is bogus so the 'change your password' form is not displayed.
* c) leak information about the validity of a token, thus allowing rapid brute-force
* attempts.
*
* The inconvenience of a real user following an expired token and being told so
* after they've set a password is a small price to pay for the improved security
* and reduction of attack surface that validating after submission affords.
