stop_code instead of stop_id

[barbeau]

From https://code.google.com/p/gtfs-osm-sync/issues/detail?id=14:

When present, consider using the stop_code field instead of stop_id to identify and show stopping point.

stop_id is often a complex value, used by internal systems of Transit Companies; stop_code is a public value instead, familiar to end users and possibly used to populate OSM.

Thanks.
