Title: Fixing Issue 686: Tooltip bug

This change addresses the bug described in Issue 686 (https://github.com/flot/flot/issues/686).
By creating a persistent tooltip div, and using jQuery's fadeIn() and hide() methods, it is no longer necessary to check if the point being hovered has changed, thereby eliminating the bug.
