title: Enable camera roll thumbnail in UIImagePickerController
body: <p>Is there a way to display the camera roll thumbnail (marked in red below) inside a UIImagePickerController?
  The right image shows what a default UIImagePickerController looks like with a camera source.</p>

  <p>This is how I present the camera:</p>
  
  <pre><code>func openCamera() {
      if(UIImagePickerController .isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera)) {
          picker!.sourceType = UIImagePickerControllerSourceType.Camera
          picker!.showsCameraControls = true
          picker!.cameraDevice = UIImagePickerControllerCameraDevice.Front
          self.presentViewController(picker!, animated: true, completion: nil)
      } else {
          NSLog("No camera")
          openGallary()
      }
  }
  </code></pre>
