title: Toggle start and stop jQuery
body: <p>i'm pretty new to this jquery/javascript stuff but i have this <a href="http://jsfiddle.net/AKgZn/2/" rel="nofollow">jsfiddle example</a>.
  So far i have it starting on click but it needs to stop on click as well and return to original state (#pause_button1) which needs to toggle. 
  Any help would be appreciated
  Thanks in advance
  :)</p>
