Supported Flags

Possible flags:

once: Ensures the callback list can only be fired once (like a Deferred).

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.
