[Christian Hergert <chergert src gnome org>]

commit 9d95d65948a39e7cb207b6f17d277ba3fa8391fa

    gui: bridge GApplication.open signal to IdeApplicationAddin.open
    
    This adds a new vfunc for application addins to open files and wires up
    the GApplication.open callback to dispatch the signal to addins.
