Title: Allows positioning of the tooltip by setting data-position to 'top', 'bottom', 'left', or 'right'.

This is just a quick feature that adds the ability to set the side that the tooltip will appear on. It also makes the little speech bubble arrow into an actual element instead of just a :before style.
