Overhaul tooltip implementation. Avoid queuing and other problems by

creating the tooltip element on the fly, never reusing it.
Use aria-describedby attribute to find the associated tooltip again.
Allows customizing animations much easier (just replace fadeIn/fadeOut),
still open.
Updated demos and visual test to replace now-missing .widget() method.
Added tooltipClass for that.
