title: Configure TinyMCE for use of Font Awesome icons in Composite C1
body: <p>I use Composite C1 CMS, but the custom TinyMCE in it is so crazy. Simple issue: we'd like to use Font Awesome icons. Source code editing is OK.
  If we add the following:</p>
  
  <pre><code>&lt;i class="fa fa-bus"&gt;&lt;/i&gt;
  </code></pre>
  
  <p>This is removed. OK then, add a space:</p>
  
  <pre><code>&lt;i class="fa fa-bus"&gt;&amp;#160;&lt;/i&gt;
  </code></pre>
  
  <p><strong>i</strong> is converted to <strong>em</strong>.</p>
  
  <p>If I change <strong>valid_elements</strong> in config in the file visualeditor.js, nothing happens, still the same problem.</p>
  
  <p>Are there any solution for this issue? Anyway it would be nice to add a button to the toolbar '<em>add icon</em>'.</p>
