Empty carousel may lead to an ArithmeticException

[ripplemotion]

CarouselLayoutManager's translatePosition method may try to divide the position by zero as there are no item available. This would occur if a user tries to scroll on an empty carousel.

	public int translatePosition(int position) {
		if (!mInfinite) return position;
		int itemCount = getItemCount();
		**position %= itemCount**;
		if (position < 0) position += itemCount;
		return position;
	}

This is an issue in my case too, I just hide the carousel when there's an empty list coming...
