changed if statements in _onTouchEnd method which were previously

... checking for GESTURE.angle_difference !== 0 and GESTURE.distance_difference !== 0 but because capture rotation and capture pinch return undefined if they are below the predetermined threshold it meant that any double touch that wasn't a pinch or a zoom (like a double tap) was still firing these events: 'pinch', 'pinchIn' 'rotate', 'rotateLeft' So just changed them to check for if angle_difference and distance_difference are truthy so a negative or positive number will pass through but undefined will not. Also added in a 'twoTap' event for when you do a double finger tap as I couldn't find any support for this anywhere. I think the coffee script is correct but not sure as I usually just do pure JS. Also couldn't find any instructions for if a build was required before committing (assume that's what Grunt is for?) but you can at least see the changes here and decide if they're worthwhile. :)
