Windows Phone 8.1 touches event support

[AlexanderPolenov]

Windows Phone 8.1 JS apps doesn't support touchstart, touchmove and touchend events. It uses pointerdown, pointermove and pointerup instead.
WP events also have the little bit different properties. There is no touches array. WP pointer events closer to mouse events rather than to common touch events.
It will be cool if gameJS will support them.
