MaximilienBizien 6b0ddb0a53 Créer menu de base
Création d'un menu principal de base.  Ce menu contient un bouton pour démarrer le jeu, un qui montre la liste des jeux, un qui montre les options et un dernier qui quitte l'application. Certaines de ces interfaces sont incomplête, mais elle seront complétés plus tard.
