Adding my CDRW device to k3b

OK, let it be clear that the cdrdao thing is a problem of the software itself
(as in: not needed to be root if done right), but certainly for us with devfs
and proper permissions and group membership this can be solved without any
problems or upstream changes. I can burn CDs alright but the GUI throws the
warning nonetheless (simply because of cdrdao not being suid root? -- suid
root shouldn't be needed at all).
I recently discovered another problem with k3b: Try to burn a 5.4-RC3 iso with
it. Booting off it wouldn't work, and after pulling out a modest amount of
hair I mounted the CD, and yes, there was one single file called blah.iso on
the CD :)
[CC'd to ports@ as a FYI so that maintainer will see this as will others who
might be interested. There really are a few problems with this port IMHO]
