Set POI - Deprecate by discovering POI via OSM

It is quite clear MissionChief uses Open Street Map for its data, but it's my opinion that this link could be better. Open Street Map has a lot of POI data already uploaded to it, which means the feature that allows end users to enter their own POI flags for their communities is rather unnecessary. Just run an OSM query for all nodes near a station and run their amenity= key tags through an internal filter. It would provide better diversity of calls, and be more scalable for everyone.
