this patch add command to lock the account to country using ip2nation.
i split the .account lock command to 2 commands.
.account lock ip on/off
.account lock country on/off
add to login country check.
add ip2nation table to auth db [empty].
so all you need to do to get this work is download the full db from http://www.ip2nation.com/

and some note… maybe its time to move this table to auth from world. even as empty table it more used in auth then world.
