Rework Nominatim results: name as label, address as full street address

Browse Source 
Name now uses the Nominatim place/building label (e.g. "The Quadrant")
when available, falling back to street address. Address field now
contains the full formatted address (house number, road, suburb, city,
state, postcode, country) instead of just the city/state portion.
