ROADMAP:
- Smooth transition on append messages (slide-in plutôt que jump)
- Détection captcha
- Bouton actualiser les messages (+ afficher le delai courrant d'actualisation)
- Bouton désactiver JVChat
- Bouton retour liste des sujets
- Notification avec @pseudo
- Blacklist
- Pouvoir voir les anciens messages
- La leftbar ne se rétrécie pas si le titre du topic n'a pas d'espaces
