Subject: [PATCH] implement tracking current window for Gnome+Wayland

Based on information from:
https://github.com/ActivityWatch/aw-watcher-window/pull/46
https://askubuntu.com/questions/1412130/dbus-calls-to-gnome-shell-dont-work-under-ubuntu-22-04
https://github.com/hseliger/window-calls-extended

To avoid opening a security hole, it is wiser to install the "Window calls extended"
extension by hseliger. Then we can regularly query the currently active window.

Compared to the previous version, activity/passivity of the user is not detected anymore.
