title: fullpage.js setAllowScrolling
body: <p>I have tried to disable the scrolling down on section 4 into section 5.
  Does not seem to respond to this:</p>
  
  <pre><code>        if(anchorLink == 'support-contact' &amp;&amp; slideIndex == 0) {
          $.fn.fullpage.setAllowScrolling(false, 'down'); 
          $.fn.fullpage.setKeyboardScrolling(false, 'down');
          }       
  </code></pre>
  
  <p>support-contact is set here (section 5 not set as it is hidden section):</p>
  
  <pre><code>$(document).ready(function() {
  initialize(false);
  function initialize(hasScrollBar){
  $('#fullPage').fullpage({
      anchors: ['home', 'livingwell', 'happybuy', 'support-contact'],
      loopHorizontal: false,
      controlArrows: true,
      menu: '#menu',
  </code></pre>
