WebGestureEvent events of subtype GestureFlingStart had a field deviceSource to specify which device was the origin of the fling request. It is useful to have this field for other WebGestureEvent subtypes (in particular GestureScrollStart, GestureScrollEnd). Previously, a single top-level field was added to WebGestureEvent. Now that Chromium populates this field, use it in the Chromium WebKit layer.
