Allowing keyboard capture for Remmina, Virt Manager and other software in GNOME Wayland

One capability seems missing in Wayland compared to X11 is the ability to fully capture keyboard events, for example when using remote desktop tools or virtual machines.

Apaprently, this is implemented differently now in Wayland, where the desktop evironment need to allow application to inhibit shortcut keys. To do this in GNOME, go do Settings > Apps > $application_name and allow Inhibit shortcuts
