[Benjamin Berg <bberg src gnome org>]

    mouse: Remove mousetweaks support
    
    The pointer accessibility features handled by "mousetweaks" cannot work
    on Wayland, so they need to migrate in the Wayland compositor instead.
    
    Remove support for "mousetweaks" from gnome-settings daemon.
