Log Message:
With the 'inet6' option, depend on djbdnscurve6 instead of djbdns.

Extract most of MESSAGE to README.pkgsrc.

Remove vestigial Red Hat chkconfig stanza from main control script (we
have pkgtools/rc.d-boot now).

Use CONF_FILES where applicable.

rc.d script defaults:
- Tag log entries like qmail-run's; for instance, "nbtinydns" and
  "nbdnscache" become "nbdjbdns/tiny" and \ 
"nbdjbdns/cache".
- Have tinydns listen on the network.
- Auto-rebuild CDBs as needed on service start.

Bump version.
