Update iso_3166 o latest Newsletter.
Ensure iso_3166_2.tab is ASCII-clean, not UTF-8

- Tidy up ISO 3166 Tables

- Add man pages documenting them.

(1) Perl code incorrectly refers to Locale::Currency module.
(2) Add the following:
	all_subdivision_codes (code)
	all_subdivision_names (code)

That parse the ISO 3166-2 files


: Missing files:
	ISO-4217
		af, ar, az, bg, br, bs, eo, eu, id, is, lt, lv, mi, mk, mt, ms, nb,
		oc, ro, sl, ta, wa

	ISO-3166
		et, fi, gl, ja, lt, mi, mk,  ms, mt, nl, nb, nn, oc, pl, pt, pt_BR, 
		ro, ru, sl, ta, uk, wa, zh_CN, zh_TW

 iso-3166/no.po truncated

- Ensure compatability with language / territory names in GLIBC Locales
  files.

- KDE:
	desktop.po file contains such information
	entry.desktop has redundant language name information

- Flags in language-env, kde i18n files overlap.

- Add entries for "ven" (Venda); no iso-639-1 code exists, but used in kde.
