Search more than callsign

[xylo04]

I don't want a massive form with a text box for each possible ADIF field. I'd like to model this after the GCP console search fields: type a field name, then colon, then the value to search in that field, and the search term visually becomes a chip. If the field isn't specified, then use full-text search.

This needs a revamp to the QSO service search facility.
