Added a Windows Gaming Input joystick driver 

This driver supports the Razer Atrox Arcade Stick

Some of the quirks of this driver, inherent in Windows Gaming Input:
* There will never appear to be controllers connected at startup. You must support hot-plugging in order to see these controllers.
* You can't read the state of the guide button
* You can't get controller events in the background
