[gnome-builder/wip/chergert/dspy: 3/11] dspy: use radio buttons for connections

    dspy: use radio buttons for connections
    
    We still want to get this setup to do delayed selection of button once
    the surface is shown the first time.
    
    Worst case, we can do that with a GAction from the menuing system.
