fixes possibility of a user password change being sent out when a password couldn't be/wasn't changed

fixed pagetools being inaccessible on screens lacking necessary height, and aligned them to content when on smaller screens

using http://cleancss.com/

Yes, it's hiding $auth, but detail templates might depend on that. We
