title: qtip2 reposition on target change
body: <p>I'm using <a href="http://craigsworks.com/projects/qtip2/" rel="nofollow">qtip2</a> to add a qtip next to the selected radio button among a set of grouped radio buttons. I can display the qtip correctly when the page loads, but when the selected radio changes, I'd like the qtip to follow along and point at the newly checked radio button.
  I have a jsfiddle <a href="http://jsfiddle.net/KHxgQ/20/" rel="nofollow">here</a> highlighting the issue. How can I get the qtip to point to the newly checked radio button?</p>
