title: simpledialog2, styles customization
body: <p>I have an app which has several types of popups, so each one should has its own CSS styles, is there a way to do this, to give a simpledialog2 a custom CSS styles but not to all of the dialogs in the app?
  I tried with:
  <code>
  $("&lt;div&gt;").simpledialog2({
  ....
  }).attr('class', 'someClass');
  </code>
  I have tried also with:</p>
  
  <pre><code>$("#myElement").simpledialog2({....,buttons : {   'Aceptar': {     click: function () { 
  },     icon: ""    }   }});
  </code></pre>
  
  <p>But it does not worked.</p>
  
  <p>I need to have buttons in the popup so I better not use "blankContent" because it does not let to close the popup only when pressing the buttons.</p>
