title: Remove a class select option is not selected
body: <p>When i select something from a selectbox it adds a class to the </p>
  
  <p>selected option this way:</p>
  
  <pre><code>$(
      'div#tabs input[type="text"],
      select option:selected,
      input:checked,
      textarea'
  ).addClass('takethis');
  </code></pre>
  
  <p>But when I select a different option it doesn't remove the class 
  <code>takethis</code> from the option which I first selected. 
  How can I force this? </p>
