Add OpenStreetMap cycle map to list of Kartographer external services
Add OpenStreetMap cycle map to list of Kartographer external services

This change should add the OpenStreetMap cycle map to the "topographic" list
of external mapping services. While I have not discussed this change,
OpenStreetMap.org's default style is already linked and OSM is a "featured"
service; ACME Mapper is currently the only map listed in the "topographic"
section; and ACME Mapper is not an official service and is a web application
built on top of maps run by others. Furthermore, although the OSM map is
primarily a cycle map, ACME Mapper's topographic map does not have coverage
outside the United States, whereas the OSM map has worldwide coverage.
