[Xymon] Bug in 4.3.18 HTTPD graph display

[Scot Kreienkamp]

OK, I finally figured it out. It was the rrdctl files and I was missing a configuration line in xymonserver.cfg.  Somehow the old version didn't care about the missing line.  It wasn't working right because it wasn't using gauge but there were still graphs there.

Thanks!
