[Lubomir Rintel <lkundrak src gnome org>]

commit c8fcd04dcfcac1a3572ea02a377dba0a21e08a50

    editor: load the GtkBuilder data from a resource
    
    This makes some useful things possible, such as running from a built source
    tree or, in future, using a modified version of the file for Gtk4 version.
