spin kickstart/minimization cleanups

[ dropping -devel since the comps changes are done, readding spins]

Ok so I pushed the spins commits with fixes suggested by people,
here's the current status.  Both of these are x86_64, I'm doing a i386
now too (which I expect to be smaller).

But basically we have a CD image again for people who really need it.
What exactly the messaging on this should be is a bit up in the air;
I'd suggest it be positioned mainly as "rescue/barebones install".
I'm going to wrangle a bit and see if I can get the live-desktop down
more.
