This patch moves the /isolinux directory on the livecd to
/boot/isolinux, and the /syslinux directory on liveusb to /boot/syslinux.
I think that this will be make the livecd appear less intimidating to
new non-linux-guru users. Aesthetics.
Since I don't use ppc myself, I didn't attempt to also move the /ppc dir
to /boot/ppc on the ppc side. But I would recommend that as well if
possible.
