[PATCH 1/1] Add support for gpaste as clipper

[Peter A. Bigot]

gpaste is a Gnome-specific clipboard solution with history.  Unlike
wl-copy, it does not rely on being able to take focus to access the
clipboard, so it works for users who prefer focus-new-windows=strict
(vice "smart") under Wayland.
