[SailfishDevel] Flatpak support by Lipstick

I don't think the Wayland window className method is the right thing for
you - on further investigation this is used by aliendalvik because of
its unusual shared window handling. Your flatpak apps wouldn't do that
sort of thing, so we can handle this more simply.
I did find where the support for X-Nemo-Single-Instance lives. It seems
to only interact with apps using the invoker:
From the other TJC question about python3, it looks like this might
still be broken, but as you're not using the invoker I don't think it
would help you as it stands. More investigation is needed into why it's
not working, but I think that patch might be too simple.
I think what's needed for flatpak and other launchers is some directive
to check the first argument as well as the binary. Will look into the
best way to do that. It'd be nice if it coped with apps that take
additional arguments too - no doubt there'll be a need to associate
flatpak apps with mimetypes. A good solution here could well obsolete
the broken single-instance completely - I'm not sure what use it has
