Zsync for livecds.

[John McCabe-Dansted]

Zsyncing ubuntu-7.10-desktop-i386.iso to xubuntu saves ~63% of
bandwidth over downloading the xubuntu.iso directly. Zsyncing 7.10 to
Hardy alpha-4 saves ~14% of bandwidth.
However Zsync requires .zsync files to be available some where on the net.

Perhaps we should add .zsync files to cdimages?

(Also, I notice that manifest and list files are available. There is
no way to actually use these to download the livecd is there?)
