    display: Don't leak GnomeRRModes
    
    GnomeRRMode is a boxed type which means that if stored as such in a
    tree model, the model creates a copy to use internally. In addition,
    it means that gtk_tree_model_get() will also get a copy which must be
    freed by the caller which we were not doing.
    
    In this case though, we don't need the copies since all the
    GnomeRRModes that we use outlive the model so we can simplify things
    by just storing a plain pointer in the model instead.
