Include request object in response-type exceptions

[Altreus]

If there is an error in a request that causes an exception, it would be very helpful if the request that caused it were also available in the exception object.

cast @jnthn.
I can fix that in a couple of lines, should we? Looks like a useful feature.

Depends on #38

When I tried getting the request from the response in the exception it said it was not defined.

I think this might help.

@Altai-man With #38 merged, is this now resolved?

[jnthn]

Ah, actually maybe should document it too.

[Altai-man]

@jnthn it is now resolved, but yes, we should document it too.
