make *all* a tags set cursor:pointer and upgrade jquery

- I pulled the newest jquery (1.x) into the repo but I haven't
  started using it yet. This fixes the warning generated in
  the chrome dev console whenever you click on the page.

  'event.returnValue is deprecated. Please use the standard event.preventDefault() instead.'
