Detect geoip - show proxy's country

[Owyn]

Description suggestions

add Country column into the program's UI where detected country of the proxy would be shown

Necessity of recommendations

many services are geo-blocked and many users use proxies solely to bypass that so now we have to add like 100 proxies, start each one of them, go to a site which shows your country, then repeat 99 times more to try to find the one proxy with the needed country
