Kartotherian: brand new OpenStreetMap tile server for Wikipedia

[source: https://www.mediawiki.org/wiki/Maps#Getting_Started]

OpenStreetMap and the Wikimedia Discovery Department have collaborated to launch a new trial map tile rendering service available at https://maps.wikimedia.org . With this service we hope to encourage our community to create tools and integrations to develop new ways for readers and editors to discover Wikimedia content. We strongly believe that our knowledge engine needs to be powered by multiple entry points and think that maps are a key discovery tool.
