    summary: show a different message on live sessions
    
    When running on live sessions, we have to make sure the user is
    well aware of the fact that anything he or she does with the system
    is transient and all the files and settings will be lost after
    the reboot.
    
    The current summary page, however, doesn't handle that case.
    
    Fix that by showing a boldened warning message, and rewording the
    other labels to clearly state the transient-ness of the live usb
    session.  Unscientific straw polls of the London team concluded that
    this is about the right point to wrap the text, and that a little extra
    margin below makes the elements look more balanced.
