make ssh2 connects working w/o the ssh-askpass utility (fix the
code how to acquire a [pt]ty pair) The user may still choose the
ssh-askpass way inside the application. That way is just no longer
forced (as i did with the last update). Now it's possible to choose
between direct password-sending from the application, or sending
the password with the ssh-askass utility.
