Tornado 3.0

[Carreau]

Apparently tornado 3.0 has been released.
everything seem to work fine, but we should keep in mind
the new and removed stuff if we have issues.

I think the main issue we have in IPython is some logging messages being lost, but quite a few APIs have changed. I will be working on updating PyZMQ compatibility this week.

I presume you are using my stdin branch - this isn't an issue on master, and I've now fixed it in that branch as well.

That's possible, I was demoing, don't remember the exact branch.

I (and presumably others) have been living on tornado 3.0 for some time, I think we can close this.
