        retourne un tableau de tableau de la forme :
                dir => "directory"      Nom du dossier
                level => 0-n            Niveau du dossier (0=racine 1,2 ...)
                put => "/sub/sub/directory" Contenu de la variable post à ajouter pour la balise A si ="" c'est le dossier courant.
        Si probleme, positionne $errbrowsefold
        Sinon, retourne le tableau et $maxlevel contient le nombre maximum de sous-dossiers.
