snapshot diff needs a -raw or -json option

It would be nice if snapshot diff could output an easily parsable format such as json.

aptly 0.9 would have snapshot diff REST API, which returns JSON objects.

I agree that having something parseable for the CLI mode would be great as well.

Beside this it would be helpful if the return value of aptly diff is identical with the diff command:

Exit status is 0  if inputs are the same, 1 if different, 2 if trouble.

csv output could also be useful.
