PATCH: Bump Locale-Codes from 3.12 to 3.13

Attached is a patch to upgrade the Locale-Codes distribution (containing
the core modules Locale::Country, Locale::Language, and
Locale::Currency) to the most recent version.

====
Background:

The core modules Locale::Country, Locale::Language, and Locale::Currency
(all part of the Locale-Codes distribution) should be updated on a
regular basis. They contain "codes" from various internet standards
which change over time.

I plan on releasing new versions twice a year to keep the codes
up-to-date. At this point, I'm not planning on any significant code
changes (other than bug fixes), so the only significant changes
betweenreleases should be to update the codes.
