Stream support

[sonnyp]

Would be nice if riak-js had first class support for Stream (http://nodejs.org/api/stream.html)

Couldn't find anything in documentation.

http://riakjs.com/#streaming_keys

Should emit 'data' instead of 'keys' to be pipeable, but it's there.

Would be nice to support streaming for data as well, as far as I can see it works for mapreduce and getAll (which is a mapreduce) but not for getting data objects by default. Would be nice so...

[sonnyp]

Yes I meant for data/value.

Looking through the http_client it should be possible to stream the data since underneath the data is already streamed to the client, the thing missing would be to include a streaming parser for the different data types, like json, which are returned in parsed form.

@sideshowcoder I think a raw stream is enough. If you need data specific streaming you can pipe the http response through a parser.
