break option inside forEach

[demian85]

I think it would be nice to include a "break" option inside an iterator to emulate the 'break' statement used in loops.
Actually I created my own by sending an extra parameter to the iterator called 'break'. It can be done just by calling the callback manually but it's not so practical to create a reference to the end callback before calling async.forEach
If you think it is useful enough I can send a pull request.

Is anyone still interested in this? I just had the same problem and couldn't find my way out of the iterator!

EDIT: I'm such an idiot, the solution is much simpler than I thought. Just call the callback with an Error and done!
