Signals.handlerBlock

Blocks a handler of an instance so it will not be called during any signal emissions unless it is unblocked again. Thus "blocking" a signal handler means to temporarily deactive it, a signal handler has to be unblocked exactly the same amount of times it has been blocked before to become active again.

The @handler_id has to be a valid signal handler id, connected to a signal of @instance.
