@nandy-andy @RafLeszczynski @rogatty Please, review ;) DO NOT MERGE JUST YET
I think this is good enough. We might extract to separate method the creation of URL and re-use, though. [Similar line when we could later reuse extracted method](https://github.com/Wikia/app/blob/MOB-1532/extensions/wikia/WikiaInteractiveMaps/WikiaInteractiveMapsController.class.php#L405) is also in the controller.
