[todo] Error message for "doesn't have an address" reads "no lat/lon in line 1"

Perhaps "street address" is also a valid column name? If that's too onerous (I could see that you'd need to start including "house address" and "palace address"), perhaps it says "no address or lat/lon on line 1" or some other way to communicate "you may have added addresses but we couldn't read them"
