Add vibration support to Gamepad and Joystick APIs

There should be a function to provide gamepad vibration capability to the platforms that is supported.

It should use any gamepad device based on its ID you provide, both left and right motors with normalized values from 0.0 (no vibration) to 1.0 (full vibration)

Windows & Xbox could be done via XInput (and DInput if you wish to also support legacy gamepads)
WiiU, Playstation 3/4 controllers also have vibration capabilities.

Gamepad vibration adds so much feedback to a game that it'd be a shame to overlook it.

I think AIR can too, idr if it's through an ANE or if it's native functionality.

Yeah, I think it's an ANE that works on Windows, Android & iOS judging from here (http://www.adobe.com/devnet/air/native-extensions-for-air/extensions/vibration.html)

As a note, I am not sure about the device vibration that ANE maps the vibration to iOS/Android though.
I'd categorize that in another API function since it affects the actual device and not a gamepad device (plus you could plug in USB gamepads on Android/iOS, which would complicate that more since the function would vibrate the device instead of the gamepad, unless you could redirect that somehow).

SDL supports it, we would just need a Lime API for it
