title: CKEditor custom stylesSet overrides default
body: <p>I'm testing adding custom stylesSet.  So in my code i add the following (per <a href="http://docs.cksource.com/CKEditor_3.x/Developers_Guide/Styles" rel="nofollow">instructions</a> in)</p>
  
  <pre><code>CKEDITOR.stylesSet.add('custom_style', [
    { name: 'No UL Bullets', element: 'ul', styles: { 'list-style-type': 'none' } },
    { name: 'My Custom Inline', element: 'span', attributes: { 'class': 'mine' } }
  ]);
  
  oEditor.config.stylesSet = 'custom_style';
  </code></pre>
  
  <p>The problem is that it overrides the rest of the default styles that comes with CKEditor.  I cant seem to figure out how to just append my new styles with the existing once.  Any ideas?</p>
