Firefox event issues

[Metalmastery]

1. Subscribing to "touchend" event ("events" object in a view) brokes "tap" and "pointerup" events in Firefox. RAD simply doesn't fire "tap" and "pointerup" events in this case.
2. Custom event timeStamp is completely broken in Firefox and returns large numbers. Due to this GestureTracker always fires a "longtap" instead of a "tap". I found that overriding the timeStamp getter works for FirefoxOS and desktop Forefox, but it looks dirty as hell.

customEvent = document.createEvent('MouseEvents');
customEvent.initMouseEvent(type, ...);
// direfox dirty hack
customEvent.__defineGetter__('timeStamp', function (){
    return e.timeStamp;
});
