Title: Updated Params controller to match Request controller

Method signature of
$this->getController()->getRequest()->getQuery($param, $default);
is public function getQuery($name = null, $default = null)
so it should be possible calling the Params plugin controller without specifying any parameters (currently you have to pass in null values).
