[ic] UK shipping UPS www lookup fix

[interchange-users@icdevgroup.org (Jeff Dafoe)]

UPS's lookup CGI doesn't accept UK as a country.  This "fix" really ignores
the Northern Ireland issue, but I don't expect many orders from there.

If someone from England picks UK from the country picklist, we want to
change that to GB when issuing the UPS query.  Modify ups_query.tag:

  $country = uc $country;
  +## JDD fix to turn UK into GB
  +if ($country eq 'UK') {
  +  $country = 'GB';
  +}
