Some GTFS feeds contain URLs for each route (http://trimet.org//schedules/r100.htm) and each stop (e.g. https://trimet.org/#tracker/stop/9826).

backend/save_routes.py is now storing these URLs in the route configuration in S3, so that it is available in JavaScript as the "url" property of the route and stop info objects.

If these URLs are available for a route or stop, it would be nice to put links somewhere in the UI so that people could easily go to the official page for a route or stop.
