[sugar etiona] Consoles and XDM login box could autologin

If the user tries to use the text consoles with Ctrl-Alt-Fn they are presented with a login prompt at which they have to guess that the username is "trisquel" and the password is blank.

Similarly if they log out or, more likely, are forcibly logged out when they change certain settings such as keyboard layout, they are presented with a mysterious login box where they still have to guess.

If autologin could be arranged that would make the system more amenable.
