    kupfer_plugins: Contain Source inside its own plugin object
    
    For fun and profit, the "Kupfer Plugins" source get a "leaf repr"
    which is the Plugin object representing itself. (So it goes recursive,
    but that's not important)
    
    This is simply what leaf_repr intended all along: reduce
    almost-duplicate objects in the catalog.
