Fill the zone box from the log and the country file on space

Browse Source 
Without a call history file, the CQ zone box stayed empty after the
callsign. It now takes the zone from the call history file, else from the
last logged contact with the call, else from the country file, as N1MM
does. A box that already holds text is left alone.
