Accessing protected properties

on https://github.com/argnist/Cliche/blob/master/core/components/cliche/controllers/clichecontroller.class.php#L43
I think it should be

```
/**
 * Return an array of REQUEST options
 * @return array
 */
public function getProperties() {
    return $this->controller->getProperties();
}
```

because the $scriptProperties property is protected inside the ClicheController class
