• להחזיר את הרישיון של התמונות בוויקישיתוף ל־cc-by #2066

Checks the attribution in parallel for all images when converting the data of a POI to be presented.
The attribution is cached, so this should not impact performance much.
Filter out images that do not have the relevant attribution.
Changed the attribution fetching to use Wikimedia commons instead of a specific language for wikipedia, this way the mechanism is more robust and doesn't require to check the user's current language.
