Compatibility with JupyterLab

[jakevdp]

I've not been able to get altair plots to show up in JupyterLab – I think @ellisonbg understands the reason for this.

Once we get that working, it would be awesome to have a JupyterLab plugin that lets us simultaneously edit Altair Python code & raw Vega-Lite JSON, with a live view of the result, kept in-sync using Altairs to_altair() and to_dict() methods.

Yes, there are a couple of things we need to do, but let's keep this open to track progress...

Relevant work:

• [WIP] Changing to MIME based rendering #216
• Refactor to use Jupyter's custom MIME type based rendering ipyvega#60

With the jupyterlab_vega extension, live editing Vega is possible 👍 :

Let's track progress at #283

Fixed in master, closing.
