Controller support for Xbox one in Windows UWP

To back @Rob Caplan - MSFT with a source, this blog from the Microsoft Developer Network states:

Windows 10: There is a new WinRT API in the Windows.Gaming.Input namespace for universal Windows apps. This API supports both the Xbox 360 Common Controller and the Xbox One controller, including access to the left/right trigger motors. The latest version of GamePad is implemented using this new API when built for Windows 10. Note that existing XInput-based Windows Store applications can link against xinputuap.lib which is an adapter for the new API for universal Windows apps--this adapter does not exist headset audio either.

Take a look at the Windows.Gaming.Input namespace. Its GamePad class is in the Universal API contract and available on all device families and languages.
