Subject: Favicons en parallèle
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Nouvelle méthode pour afficher les favicons à la demande et en
parallèle.
Déplacement du dossier des favicons sous /data/favicons/
Devrait permettre de fermer le problème d'import OPML
