Ivan added support to build everything on Debian/Raspbian stretch, added
some alternate URLs, and updated the "just how the hell do you install
Marinetti right now exactly?" dance.
This was more frustrating to merge than it honestly should've been and
I'm kinda responsible for some of that, but it's never gonna get easier
to maintain unless we break from the single-developer monolithic blocks.
Hopefully this will be the last time we do things this way.
