/*****************************************Modifications:************************************
- Modifications de phile                                                                                       
 lignes 33 a 48, le script fonctionne a condition de ne pas afficher les coordonees dans la liste deroulante des villes
- Modifications de Yog-Sothoth                                                                                       
ligne 40 pour que cela fonctionne avec les coordonnees, remplace "2" par "7" car l'espace est note   soit 5 caracteres de plus
Ligne 207 car sinon le nom de la ville pour l'update du fichier config de firefox ne tenait pas compte de la fonction getcityname modifiee et l'update se faisait avec l'ancien script .
Reste a voir: le script plante si on change de ville quand on est sur la page de chargement, mais si on passe par le port tout va bien :)
