API to check for active tweens about tweenjs

[gskinner]

This seems like a reasonable feature to add, and should be quite simple (as you've indicated). I'll take a look at adding this in the next day or two.

I'll likely extend the concept a little bit, so you can also check for tweens on a particular target. Something like:

Tween.activeTweens(target); // returns true or false, if target is undefined, checks if there are active tweens on any target.

Thanks,
Grant.

Please add an API that would allow a client script to check whether there are any active Tween objects. I had to use an undocumented Tween._tweens property in my code to work around this limitation:

function tick(delta)
{
        if (Tween._tweens && Tween._tweens.length > 0)
        {
            Tween.tick(delta);
            _update = true;
        }
        if (_update)
        {
            _stage.update();
            _update = false;
        }
}

I finally got around to adding this as:
Tween.hasActiveTweens(target);

If target isn't specified, it will check for active tweens on any target.
