    ephy-node-view: added ephy_node_view_get_iter_for_node()
    
    The EphyNodeView is based on the following stack of models:
    
    Sort model -> Filter model -> EphyTreeModelNode
    
    This function returns a GtkTreeIter pointing to a row in the sort model from
    a EphyNode that belongs to the EphyTreeModelNode.
