unicode.7: Update to reflect past developments

The unicode(7) page will look more modern with few small changes:

- drop old BUGS section, editors cope with UTF-8 ok these days,
  and perhaps the state-of-the-art is better described elsewhere
  anyway than in a man page
- drop old suggestion about avoiding combined characters
- refer to LANANA for Linux zone, add registry file reference
- drop a reference to an inactive/dead mailing list
- update some reference URLs
