Title: label for unknown continent same as for unknown country

When ```GeoIP_country_name_by_name()``` cannot find country name, ```get_geoip_data()``` returns **"Location Unknown"** for country name as result.
When same happens for a continent, we should get **"Location Unknown"** too instead of just "unknown".
