Change subject: WikidataPageBanner::getWikidataBanner added
......................................................................
WikidataPageBanner::getWikidataBanner added
A function getWikidataBanner() is added, which fetches a banner for an article
page if the page has an associated item page and a banner statement in wikidata.
The function returns the banner image name on wikimedia commons or 'null' if it
fails to achieve the above objective.
