[clutter] conform: Add a suite for the Actor scene graph API

[Emmanuele Bassi <ebassi src gnome org>]

    conform: Add a suite for the Actor scene graph API
    
    Verify that insertion and removal maintain a stable graph, with pointers
    to the various children. This should help out tracking regressions in
    the scene graph API.
