title: ExtJS MVC: should controllers be specified within requires for application?
body: <p>If an Ext.application has the following controllers:</p>
  
  <pre><code>Ext.Loader.setConfig({enabled:true});
  
  Ext.application({        
      name: 'MyApp',
      appFolder: 'app',
  
      controllers: [
          'Ctrl1',
          'Ctrl2'
      ],
  
      launch: function() { ... }
  });
  </code></pre>
  
  <p>should it also include the controllers in <code>controllers</code> in the <code>requires</code> section, i.e. add </p>
  
  <pre><code>requires: [
      'MyApp.controller.Ctrl1',
      'MyApp.controller.Ctrl2'
  ],
  </code></pre>
  
  <p>within the above class?</p>
