Add firewalllogcountry, based on firewalllogip

Add menu option to display firewall logs per country.

Ideally, I would have wanted to do a cleanup of firewalllog*.dat and showrequestfrom*.dat, and consolidate them all into one firewalllog.dat and one showrequestfrom.dat file.
But that would require changing the handling of query strings, which now seems to be based on a commaseparated string instead of URL parameters when doing a HTTP GET.
