Nightlies

While trying to fix the wpa_supplicant issue (ticket #8603), I decided to upgrade a machine to a newer version of FreeBSD. At the time, the feedback from testers indicated that the problem was local to my machine, and not within the build system. Unfortunately the system upgrade didn't go as smoothly as planned, which placed a nicely sized wrench into things. The nightly-image uploader script is running now and some time later today a new set of images will be online.
