places: a description the community shared is credited to the TREK community

A community description laid over OSM details or an index row showed up as
OpenStreetMap under ODbL, or as the place's own website. It now has a source of
its own, community, credited as TREK Community under CC BY 4.0, like the
service publishes it.
