LangNames now contains the language codes for all languages available with OS4.1, plus
Welsh (http://aminet.net/package/misc/misc/welsh_lang). There are no other 3rd party
.language files available for OS4 that I am aware of, but any new ones can easily be
added if/when they become available.
These may now not be exactly the same as the RISC OS names, but that can be resolved
by renaming directories for new translations (current ones are OK), or reverting back
to the AmigaOS names for Messages files paths.
