    GtkApplicationWindow: deal with remote actions
    
    Deal with remote action invocations correctly by implementing
    GRemoteActionGroup in the same way that GApplication does and pushing
    remote activations through the before/after_emit functions of the
    GApplication associated with the window.
    
    This is the last part of getting the threading situation right.
