    application: allow overriding startup
    
    The startup vfunc comes from GApplication, and therefore any children
    of a GApplication that overrides this function cannot call the
    application parent code that handles the startup.
    
    We would like to be able of subclassing nautilus application, and doing
    custom handling in the startup vfunc, but still use the code of the
    nautilus application that already deals with it.
    
    For that, we need to create a new vfunc in nautilus application that
    will be called when the GApplication startup vfunc is called, so
    children can override it and still use the nautilus application code
    handling.
    
    This will be needed for upcoming patches when we will create a
    desktop application.
