    vm-configurator: Default to PS2 input bus
    
    We should default all input devices to use PS2 input bus.
    This is the same behavior of virt-manager. See
    https://github.com/virt-manager/virt-manager/blob/master/virtinst/devices/input.py#L40
    
    https://bugzilla.gnome.org/735768 Doesn't seem to be reproducible
    anymore.
    
    The exception is the tablet device, that will use USB input bus.
    
    Related to #272
