 memory: Keeps 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: Ensures a callback can only be added once (so there are no duplicates in
the list).
 stopOnFalse: Interrupts callings when a callback returns false.
