wayland: initial support for showing the desktop
* Wayland: Support rendering the desktop *Wayland support is optional via the --enable-wayland option * eel-editable-label-c: remove unused variable This was leftover from earlier code compatable only with x11 * Fix gtk-layer-shell-0 version check, improve error message when Wayland requested but not found
