PATCH: Bump Locale-Codes from 3.12 to 3.13

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
  between releases should be to update the codes.
