title: jQuery Sortable without jQuery UI
body: <p>I am in need of "Sortable Drag &amp; Drop" functionality and I'm using jQuery. I can't really use jQuery UI, because for this project it would be an overhead (I'd need to add many KB of JS and CSS only to use small part of functionality).</p>
  
  <p>Is there any plugin that you could recommend or maybe a simple implementation path, that I can follow?</p>
  
  <p><em>The solution must be as lightweight as possible, preferably based on jQuery/Sizzle or pure JavaScript.</em></p>
