 // Variable to track if a captcha challenge was issued. If this gets set to
 // true, it stays that way until we are told about successful login from
 // the browser.  This means subsequent errors (like invalid password) are
 // rendered in the captcha state, which is basically identical except we
 // don't show the top error blurb "Error Signing in" or the "Create
 // account" link.
