title: Responsive jssor with fixed height thumbnails
body: <p>I'm trying to make a responsive jssor slider with thumbnails, but the thumbnails always should have the same height. I've set the <code>ThumbnailNavigatorOptions.$Scale</code> to <code>false</code> and put the thumbnail navigator into a wrapper (as suggested <a href="https://github.com/jssor/slider/issues/10" rel="nofollow">here</a>), but it doesn't work. The thumbnail navigator is scaling. If I remove the wrapper, it doesn't scale, but the layout is screwed up. Also the thumbnails should be always centered horizontally.</p>
  
  <p>Here what I've tried (if you put that html into the <code>demos-jquery</code> folder of jssor, it will load):</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;

  &lt;/head&gt;
  &lt;body style="padding: 0; margin: 0; font-family:Arial, Verdana;background-color:#fff;"&gt;
      &lt;!-- it works the same with all jquery version from 1.x to 2.x --&gt;
