[NetworkManager-vpnc/lr/gtk-4.0: 7/15] properties: load the GtkBuilder data from a resource

[Lubomir Rintel <lkundrak src gnome org>]

commit 3b5b1f78574268558541de5121a4a16d7a210bd3
Author: Lubomir Rintel <lkundrak v3 sk>

    properties: 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.
