Show bus stops and coach stations on trip map.

Add case "bus" to get_locations() and bus route handling to
get_trip_routes() in trip.py. Coach stations now populate a dedicated
"coach_station" dict instead of the train station list. Add
"coach_station" (🚌) and "bus_stop" (🚏) emoji types to map.js.
