Class: Scroller
	The Scroller is a class to scroll any element with an overflow (including the window) when the mouse cursor reaches certain buondaries of that element.
	You must call its start method to start listening to mouse movements.

Arguments:
	element - required, the element to scroll.
	options - optional, see options below, and <Fx.Base> options.

Options:
	area - integer, the necessary boundaries to make the element scroll.
	velocity - integer, velocity ratio, the modifier for the window scrolling speed.
	onChange - optionally, when the mouse reaches some boundaries, you can choose to alter some other values, instead of the scrolling offsets.
		Automatically passes as parameters x and y values.
