title: Yii Framework not returning proper WebUser class with Yii-user extension
body: <p>I have <a href="http://www.yiiframework.com/extension/yii-user" rel="nofollow">Yii-User</a> installed inside of Yii webapp. However, if I print out the User object using this: <code>Yii::app()-&gt;user</code> I get CWebUser class instead of the <a href="http://www.yiiframework.com/extension/yii-user" rel="nofollow">Yii-user</a> extended class WebUser.</p>
  
  <p>My main.php config is setup as below:</p>
  
  <pre><code>
      ...
      'components'=>array(
          'user'=>array(
              // enable cookie-based authentication
              'allowAutoLogin'=>true,
              'loginUrl' => '/user/login',
              'class' => 'WebUser',
           ),
      ),
      ...
  </code></pre>
