Subject: commands: ajout d’une commande pour lister les propriétés des cours

Pour pouvoir analyser plus facilement les attributs d’un cours, un
nouvel outil est rajouté pour lister tous les attributs d’un ou
plusieurs cours.  Il fait appel au parseur et permet de sélectionner
une source, et de limiter le nombre de cours affichés.
