About to drop in generated docs from the new 'tuxpaint-docs' repository.
As the directories will have more explicit names (e.g., "fr_FR.UTF-8"
rather than just "fr") and Spanish ("es") and French ("fr") already
exist (though they are very basic samples, 99+% untranslated so far),
renaming the current directories to match.
Stop using old `lynx`; use `links`, and use UTF-8 codepage for
output (for Russian, Chinese, etc. to still work right).
Regenerate all TXT versions of docs available in HTML.
