Now with cookie and faster modal window load. Euh, fast is not the
right word. It notifies user earlier than before. The total loading is
still the same.

Oh, for the demo user, use demo@wimm.littlebrain.org for the email and
demodemodemo as the password.

update (few minutes later ...)

ups, I think I made a mistake with the cookie. If you use "remember me" option, you couldn't logout. The only way to logout is remove the cookie.
