0017667: The command "processmaker help OPTION" shows PHP warnings if the option doesn't exist SOLVED

al ejecutar el comando processmaker help con una opcion que no existia daba un error que no era entendible para el usuario
se soluciono agregando un array que jala todas las opciones y una condicion que al dar cualquier opcion que no este listada dira que no existe
