    plugin.trash: Hide toplevel trash source
    
    It is not completely optimal, but we reuse the InvisibleSourceLeaf
    trick for the trash plugin. This makes the trash item behave just like
    it did before (as an object in the catalog, not a catalog itself).
    
    I personally see no use of having the *contents* of the trash in the
    toplevel catalog, so no reason to make it possible.
