title: Add a custom format option to CKEdtitor?
body: <p>I'm sorry if this question has been asked before, I've tried googling/looking on here/browsing the CKEditor forums and not come up with anything that I can seem to understand and implement (apologies, I'm not that great at this JavaScript stuff)</p>
  
  <p>Basically, I want to add one custom option to the format dropdown list of CKEditor, it should create a span with a class like below:</p>
  
  <pre><code>&lt;span class="custom-font"&gt;&lt;/span&gt;
  </code></pre>
  
  <p>I've tried using the below in the "config.js" file, but it doesn't seem to work:</p>
  
  <pre><code>config.format_tags = 'p;h1;h2;h3;h4;h5;h6;pre;address;div;span'
  
  config.format_span = { element : 'span', attributes : { 'class' : 'cutsom-font' } };
  </code></pre>
  
  <p>Can anybody point me in the right direction here?</p>
