new resource: ip2c (#405)

This PR separates the ip2c logic currently present in admin into it's own resource and modifies admin, admin2, and scoreboard to use it's exported functions. 

* Move admin ip2c code to new resource + Update scoreboard countries

* IP2C fixes (see description)

move ip2c inside [admin] + Remove admin2 ip2c implementation + fix getPlayerCountry call in admin admin_server.lua + fix update admin panel when IP2C starts/stops + update gitignore

* ammend b3fecd9

* Fix admin2 and admin2 client panel country flags + admin2 detects ip2c start/stop

* Add latest IpToCountryCompact.csv

* Ignore further updates to the IpToCountryCompact.csv (.gitignore)

* Readd "useip2c" setting to automatically start ip2c resource in admin/admin2

* Add getCountryName (shared) + GUI improvement in admin2/admin

* Add /testcheckflags to find missing flag images and invalid flag images

* Commented unused country flags in meta.xml + Add test script to check if any unknown codes in CSV

There are no unknown country codes in CSV now, it's good 👍

* Del /testcheckcsv (temp cmd)

* Update us.png

* Optimiziation + aHandleIp2cSetting() call order fix
