 * Implementation of hook_validate_address_fields
 *
 * This hook is used by cck_address and any supporting modules which add country-specific field validation.
 * The first argument is an array, passed in by reference in 'fieldname=>error string' pairs. The error string should remain empty
 * so long as there are no errors. If there is an error, the string should be replaced with an appropriate t-ified message. The
 * second argument is the country code of the address. The first thing an implementation of this hook should do is check to see if
 * the country code matches the country for which the module was made to support. If not, it should return immediately, without
 * modifying the $errors array. This will ensure that only the country which SHOULD validate, does the validation. The third argument
 * is the item containing the values of the form.
