Fixed very nasty bug in short_station_listing.
Fixed very nasty bug in short_station_listing.

The line assigning the initial value to listing was of course setting
listing to be a REFERENCE to station.name, and not the VALUE. So any
subsequent << of the 'color dots' was appending these also to the model's
name attribute. Ouch.
