PR adds support for FreeBSD.
I moved the original backlight module to xbacklight.c and implemented a new one that doesn't rely on XRandR as I couldn't get it to work under freebsd on my hardware.
I haven't been able to confirm that it works because I don't have a FreeBSD environment, but I will ready and confirm soon.
Merge for now and fix any problems after the merge.
