msg.blob should be named msg.buffers

To match the Notebook websockets

I think buffers is a bit of a misnomer. But since jupyter-notebook and jupyter-client use this name, jmp'd better do the same.

I guess the messaging spec should also be updated too (here and here).

Yeah, I agree. I mostly care about consistency since we have a light abstraction layer that works across the websockets and zmq in enchannel. This was the only field that differed.

I think I'll start out with opening an issue on jupyter_client before I make any PRs.
