Usenet control messages

I've finally (almost) finished fixing the Usenet control message archive system that feeds ftp.isc.org /pub/usenet/control and /pub/usenet/CONFIG. Almost just because there's still some old script running that's copying over the wrong files at the top of each hour, and so far we haven't been able to find the crontab entry to turn it off.

And I should probably do something about synchronizing the Microsoft groups and haven't done that yet.

But those are minor things. Otherwise, it's done. Nearly 2,000 lines of code, although a lot of that is for a simple NNTP daemon that I'm going to put back into INN along with various support libraries that will be useful for other INN work.

I haven't fixed the n.a.n archive, but that should be fairly easy now. That's next on the list, as well as writing up documentation for this whole system and actually releasing it publically in case anyone else wants to use it.
