Warning re ZeroMQ version 3?

[timholy]

I see you wrote some docs for ZMQ, thanks!

There might be a couple more things to add:

• Long ago I tested the budding v3 of the ZeroMQ library. It was horribly broken; if it still is, I wonder whether a warning to install v2 would be appropriate?
• At one point I added links back to Julia on the ZMQ website. With the new package location, those may be out-of-date.
• The ZMQ online manual has translations of their introductory examples into many languages. I never got around to writing any Julia ZMQ demo scripts and submitting them to ZMQ. You don't need to either, but if someone is interested it might be a nice touch.

Thanks for making a note, it does require a warning. I was working on it a couple of days ago. I've changed the send/recv calls to be compatible with the v3 interface, but it still doesn't work properly.

I've changed the links at zeromq.org, thanks for pointing them out.

I had created some of the examples in the old repo, havent ported them over to the new api. Will create a new issue for that.

Nice work!
