I changed the scripts that clearly stated where rawhide references
were to be commented out, but there are some rawhide references in
atomic stuff that may or may not need to be changed.
Now the switch between using the rawhide repo and the normal repos
can be done by just switching comment lines in one place
(fedora-repo.ks). (Note that the repo lines in fedora-install.ks
don't get changed for branching.)
