mnews: a NetNews reader

mnews is the popular NetNews reader in japan.

I think my ports and modifications are now converging,
so here it goes. Try it.

Documents are mostly japanese, but the packaged one is
configured in ENGLISH and connects to out-of-the-box.
Also “switch LANG” key is explicitly killed, so that
non-japanese users will have less trouble.

oops, it still won’t put "From: " in the post, so
you may want to
echo ‘news_field:From: <your@mail.addy>’ > ~/.mnews_setup
