DeviceOrientationCamera rotation?

[tbgeorge]

Hey all, 

I'm trying to get the rotation of a DeviceOrientationCamera in the same way I get it from a FreeCamera by saying 

var camera = new BABYLON.FreeCamera("freeCam", BABYLON.Vector3.Zero(), scene);
// var camera = new BABYLON.DeviceOrientationCamera("deviceCam", BABYLON.Vector3.Zero(), scene);
var rot = camera.rotation;

but this doesn't work. If I move the FreeCamera around with my mouse, the rotation is updated and constantly changing while I'm moving the mouse, but the DeviceOrientationCamera doesn't update the rotation variable when I view it on my cell phone. Is there a different way to get the camera's rotation that I'm missing?

DeviceOrientationCamera uses the camera.rotationQuaternion property, if I read the recent PR  right.

This is correct
