 * Possible flags:
 *
 *    once:                   will ensure the callback list can only be fired once (like a Deferred)
 *
 *    memory:                 will keep track of previous values and will call any callback added
 *                                    after the list has been fired right away with the latest "memorized"
 *                                    values (like a Deferred)
 *
 *    unique:                 will ensure a callback can only be added once (no duplicate in the list)
