   3440 *
   3441 * By default a callback list will act like an event callback list and can be
   3442 * "fired" multiple times.
   3443 *
   3444 * Possible options:
   3445 *
   3446 *	once:			will ensure the callback list can only be fired once (like a Deferred)
   3447 *
   3448 *	memory:			will keep track of previous values and will call any callback added
   3449 *					after the list has been fired right away with the latest "memorized"
   3450 *					values (like a Deferred)
   3451 *
   3452 *	unique:			will ensure a callback can only be added once (no duplicate in the list)
   3453 *
   3454 *	stopOnFalse:	interrupt callings when a callback returns false
