Live image configs moved

[Jeremy Katz]

I meant to get to this a little while ago, but then the world exploded.
Anyway, the kickstart configs for all of the various live images now
have their canonical location in the spin-kickstarts git repo
(http://git.fedorahosted.org/git/?p=spin-kickstarts.git;a=summary).  

I've removed the configs from the livecd-tools repo, leaving just the
minimal test config because it's handy to have around.  

Also, I'd like to do a release this week with all of the changes which
have accumulated.  If you've sent a patch and I haven't applied it,
assume that I missed it and please resend. :-)
