mirrors.fp.o subpages now in fedora-web

[Matt Domsch]

I moved all non-MirrorManager content that's in the mirrors.fp.o/ site
into the fedora-web module.  Right now that's only the releases.txt
file used by preupgrade, but if there's a need for more stuff there in
the future, it can be managed like all other fedora-web content now.

Thanks,
Matt
