Subject: [PATCH 1/6] compositor: Ignore some of the builtin keybindings
Mutter on wayland currently has a bug where it crashes if the run dialog
keybinding is pressed. No one notices the bug for gnome-shell, since
gnome-shell overrides mutters run dialog keybinding.
This commit makes GNOME Kiosk also override the keybinding to avoid the
crash. At the same time it neuters a few other builtin keybindings that
aren't so useful to GNOME Kiosk.
