Say hello to GenericDevice

GenericDevice can be used to deliver events to Qt3D from any device
which is not handled already by Qt3D.
What the user need to do is to instantiate a GenericDevice object,
set GenericDevice::axesMap and GenericDevice::buttonsMap properties,
then use GenericDevice::axisEvent and GenericDevice::buttonEvent signals
to deliver the events.

[ChangeLog][Input] added GenericDevice
