[gnome-games/wip/aplazas/gamepad-event: 9/14] gamepad: Handle 'event' signal from RawGamepad

[Adrien Plazas <aplazas src gnome org>]

    gamepad: Handle 'event' signal from RawGamepad
    
    Make the Gamepad class handle the 'event' signal from RawGamepad instead
    of any other event signal from it.
    
    This will be used to propagate gamepad events in a simpler way.
