  18   * login_anon.php logs a user in anonymously without having to enter a username
  19   * or password.
  20   *
  21   * Depends on two global configuration variables:
  22   * allow_anonymous_login - bool which must be true to allow anonymous login.
  23   * anonymous_account - name of account to login with.
  24   *
  25   * TODO:
  26   * Check how manage account is impacted.
  27   * Might be extended to allow redirects for bug links etc.
