Ajout d'une fonction pour linéariser un peu la réponse du projecteur (illuminate.c)

Ajout d'une moyenne sur 8 valeurs pour la luminosité (mais on garde la valeur instantanée pour altérer la couleur)
Correction du vumeter qui s'initialisais à 1px par 1px au lancement de l'appli.
Avec le lud-msi, le projo à Ju et les sons enregistrés par Laurent, ça pète pas mal :P
