title: Passing data to widget in CKEditor
body: <p>I made a very simple custom widget, however I want to add it to the editor via a custom button instead of a toolbar button so I use <code>editor.execCommand("mywidget")</code>. The widget is added correctly, but how do I pass data to the widget via this <code>execCommand</code> call? In the <a href="http://docs.ckeditor.com/#!/api/CKEDITOR.editor-method-execCommand" rel="nofollow">docs</a> it says that the second parameter to <code>execCommand</code> is used to pass data to the command handler, however I can't seem to find HOW do I access that in the widget code after I call <code>execCommand("mywidget", {paramshere})</code>.</p>
  
  <p>Thanks!</p>
