Check whether IP::Country::Fast is still needed

The only grep hit I see is in bin/checkconfig.pl, and there's also a reference in http://wiki.dreamwidth.net/wiki/index.php/Dreamwidth_Scratch_Installation#Install_Perl_modules_with_CPAN .

I was the one who added IP::Country::Fast to that wiki page just over a month ago, and I did so based on the output of bin/checkconfig.pl. So it's possible that that reference only exists there because it was in the config checker. I'll take a look around and see where it comes from.

So it seems IP::Country::Fast was used by the LJ code when we forked (in the Writer's Block feature), but along the way Writer's Block was removed (commit 5b19bf1) and then later the function that actually used IP::Country::Fast disappeared too (commit 2486cf7).

We should be able to remove the check from checkconfig.pl without issue, so far as I can see!
