SubjectRe: [ketchup] patch to alt urls for local trees

Argh, you ask, I do!

Man, a day with python really makes you hate it! ;-)
OK, I'm a perl guy, and I'm much more comfortable with that. But I did
manage to get python to do what I wanted.

If you add a 6 element to the version_info tree, it will be used as an
alternate url. I tested this a little, and it seems to work. Might want
to review it though. I'm still not comfortable with python, and I only did
some small tests. Basically I checked to see if it would work if it had
the 6th element, and if it didn't. But not much else was done to test.
