Feature request: DefaultDeferredManager.when returns MultipleRejects

I want to know exactly which deferred resolved or rejected. Seems it can't be achieved now.

@tramchamploo thnx for the request! jdeferred semantic is based on jquery's deferred object semantic.

it'd be great if you could help propose what a new semantic should be for this, since if it needs to return multiple rejects, it'll have to wait for all promises to finish. I feel this may be similar to promises.all(...), similar to this:

Since the all(...) method is assign to a different feature, it's really hard to think up a new semantic for this. So es6 doesn't have this feature yet?

Here is an experimental implementation around es6 semantics:

IIRC, the all semantic is also failing fast.

This should be addressed by #128, ptal!
