Options

. am�lioration de la YUV 8bpp 

 . nettoyage du code de gestion des m�thodes vout
 . nouvelle option --vout
 . pr�paration de l'�clatage de l'audio output comme �a a �t�
  fait avec le vout.
 . nouvelle commande --long-help

La s�lection de la m�thode vout est encore plus simple. Pour s�lectionner
le framebuffer par exemple : "vlc --vout fb". Par d�faut, X11 est choisi.
