radns in FreeBSD ports

radns is now in the FreeBSD ports system as dns/radns. Yay!

This means I have three programs in ports: kbdscan, a small program to show raw keyboard scancodes in the console (misc/kbdscan – I would have chosen sysutils, but I didn't commit it), my window manager mcwm (x11-wm/mcwm) and now dns/radns.

Yes, I know that rtsold in the coming release, FreeBSD 9, also supports the RDNSS option in IPv6 RA. Still, radns is more portable to non-BSDs and has had RDNSS support longer.
