[gimp] Add new vfunc GimpContainerView::insert_item_after()

[Michael Natterer <mitch src gnome org>]

    Add new vfunc GimpContainerView::insert_item_after()
    
    The new function is called after the item is inserted. This is a much
    smaller change than turning all vfuncs into signals just to be able
    connect_after to one of them.
