title: jCarousel - option scroll
body: <p>i'm trying to port my application to last version of jCarousel</p>
  
  <p>seems that option 'scroll' (the number of items to scroll by) is remove from options. is this right? accordingly to docs, it is present in 2.x version but not in 3.x</p>
  
  <p>simple code like this</p>
  
  <pre><code>$('#.jcarousel').jcarousel({
      'scroll': 4
  }); 
  </code></pre>
  
  <p>not apply 'scroll' to carousel</p>
  
  <p>someone have got the same problem?
  is there some workaround to solve?</p>
