xfway: added support for alt-tab switcher

[Gaël Bonithon]

Hi adlo,

> The executable is currently called "hopalong".

Oh sorry, I got stuck on xfwm4-wayland-shell. I think I tried hopalong at the very beginning and it didn't work for some reason, so I settled on xfwm4-wayland-shell and stuck with that, maybe because the name is more evocative.

So I'm able to run this compositor now (whatever it's called :)), with the executable I managed to build earlier.

I tried to run the panel quickly and there are some issues with motion events (partly of this type [1]), grab handling and placement of the panel on different outputs, but maybe this is partly fixed in the latest version. So I'd have to build it first.

Both with Wlroots 0.15.1 and with Wlroots-git.
