    ModalDialog: add 'default' pseudo-class to default button
    
    Add 'default' parameter to setButtons, that controls the binding
    of Return (unless overridden) and applies the 'default' pseudo-class.
    Currently it has no effect, but it will start having after the
    login dialog redesign.
