title: scrollOverflow / slimScroll not working properly in fullPage.js
body: <p>This is the sequel of <a href="https://stackoverflow.com/questions/20111272/scrolloverflow-not-working-in-fullpage-js">this</a> thread. </p>
  
  <p>On one page of the website I'm building for a client, both fullpage navigation and scrolloverflow/slimscroll work fine. </p>
  
  <p>On another page, fullpage nav works but the overflow is not scrolling. Looks like the two divs with the class <code>.slimScrollDiv</code> and <code>.scrollable</code> are not being created as expected.
  Here's the <a href="http://jsfiddle.net/7PwsS/328/" rel="nofollow noreferrer">jsfiddle</a> ; the <code>scrollOverflow</code> is set to <code>true</code> yet the overflow of the second section does not scroll.</p>
  
  <pre><code>$.fn.fullpage({
      scrollOverflow: true
  });
  </code></pre>
