Change releasever to a command line option (#667474)
The release version of the running system may not be the release you
want to build the livecd for, or the rpmdb may not be accessable from
the build environment (koji and chroot) so set the value to use for
$releasever in kickstart repo url's by passing --releasever=VER
If $releasever is used and no --releasever is passed it will try to
use the system's version. Under some circumstances (chroot environments
like koji) this isn't possible so an error will be raised.

=head1 REPO EXTENSIONS
livecd-creator provides for some extensions to the repo commands similar
-to what yum supports. The strings $arch, $basearch and $releveasever
+to what yum supports. The strings $arch, $basearch and $releasever
are replaced with the system arch, basearch and release version respectively.
+When no --releasever is passed it defaults to the current system's version.
The allows the use of repo commands such as the following:
repo --name=fedora --mirrorlist=http://mirrors.fedoraproject.org/mirrorlist?repo=fedora-$releasever&arch=$basearch
+Note that in a chroot environment (like koji) the rpmdb is not available,
+so either don't use $releasever in that case, or pass --releasever=VER
