Gyro normalization value in Windows improved 

SDL2 provides different gyro readings between Windows and Linux/Mac for
the Switch Pro Controller. To keep the natural sensitivity scale intact
(in-game turn = controller turn), the normalization factor is handled
differently by platform, at least for now.
Also, now giving info when there's no gyro sensor available/detected.
And green light for the DualShock 4, because why not :)
