Title: Backgroundjobs

Updates the `backgroundjobs` module and adds both a test suite and an illustrative notebook. I actually realized, in the conversation on gh-844, that this was pretty useful code.

I don't have time now to complete bringing the `%bg` magic back, but that would be pretty easy. But otherwise I think this is useful code.

BTW, right now if one moves to a new cell with a background job printing in an old one, and execute the new cell, futher output from the old bg job shows up in the new cell. It seems to me that we should be able to track the origin of the messages and ensure that they continue appearing in their cell of origin. But I've run out of time to dig into that part of the code, so unless @minrk or @ellisonbg knows off the top of your head how to fix that, we can leave it for later. But it would make for very neat and useful patterns, leaving tasks in the background that continue updating a given cell...
