Added a new feature from Peter Eriksson's latest release of ypserv (0.13):

register ourselves as an NIS version 1 UDP server to pacify older SunOS 4
ypbinds that seem to insist on having one around. All this does is allow
ypserv to respond to DOMAIN_NONACK requests that are periodically
transmitted by ypbind: the server will not actually work as an NIS v1
server in any other way.

Unlike the mainline code, which implements this as a compile-time
option, this feature can be turned on with the newly-added -k flag
at runtime.

Bunped version number to 0.13. (What the hell.)

Updated the man page to reflect this change, also made a couple of small
edits to reflect the recent changes in the /etc/rc* setup.
