title: disabled touch on mobile owl carousel
body: <p>this is in my script</p>
  
  <pre><code>$("#owl-caro").owlCarousel({
      items: 4,
      itemsDesktopSmall:[979,4]
  
  });
  </code></pre>
  
  <p>but I want to add an option, touchDrag : false when it's mobile. Should I rewrite like this?</p>
  
  <pre><code>$("#owl-caro").owlCarousel({
      touchDrag:  false
  });
  </code></pre>
