add Debian packaging

The world is becoming quite the Ubuntu-oriented place, in the Linux side of
things...

Hopefully, things should work nicely for installing on Debian, but I'll
have to admit that my main goal is aimed at Ubuntu users. Appearing in the
Application menu, being selectable in the menu editor, that kind of stuff
would be nice.

But a basic package at first would be already a good improvement!

The Ubuntu-specific thing (although it might actually be GNOME-specific, I'm not
sure) I had in mind was the Applications -> Add/Remove Applications tool. It'd be
really neat to be able to go in there, type in "quadra" in the search box and see
Quadra appear. At the moment, there would also be a need to check the "show
unsupported applications" checkbox, of course...

To have this work involves the Quadra package actually getting in their repository
(is someone a MOTU? I could become one, I suppose), but I don't know what the package
needs to do in order to show up there (obviously, not every package shows up there!).

Even without that particular feature (which could be spun off in its own issue), it'd
be nice if Quadra appeared in the Applications -> Games menu once the package was
installed, even if you do it with "dpkg -i". This is looks like it's simply a matter
of the package having a /usr/share/applications/quadra.desktop file, or something
like that...

I don't think you'd need to become a MOTU. I think you just need to point them in the
direction of an actively maintained package.

We won't hold up the 1.2.0 release for that. The Debian (and others) packaging will
at first be applied as diffs part of the package itself, and we'll do our best to
integrate those upstream.

That'll also give package maintainers the chance to work out the kinks for themselves
without round-tripping with us or having defective packaging in the upstream release.
