[gnome-builder/wip/chergert/layout] editor: add save-as action

[Christian Hergert <chergert src gnome org>]

commit 35c86efc3f5998aa542fbaa84678e2df8a3c78f8
Author: Christian Hergert <chergert redhat com>

    editor: add save-as action
    
    This brings back the save-as action and wires it up to the
    <Primary><Shift>S accelerator.
    
    This also changes the implementation to use GtkFileChooserNative
    which should be a bit nicer for us inside of flatpak.
