I'm embedding phosphor 0.7.0 for the time being (with cherry-picked commits to make it work with TS 2.1), since Gordon already packaged 1.0.0 and it's unclear if he has time to package the older version.

I'll bump the Build-Depends for ipywidgets to 6.0.0 and try un-reverting the "Port SageNB interacts to Jupyter" commit, and see if our Sage 7.6 still tests successfully.

Sage's tests relating to ipywidgets 6 fail, but succeed (with notebook 4.2) when I apply their patch:

https://git.sagemath.org/sage.git/tree/build/pkgs/ipywidgets/patches/widget_repr.patch?h=develop

This is already filed upstream:

https://github.com/jupyter-widgets/ipywidgets/pull/1031

Unfortunately it looks like upstream want behavioural changes, so I don't think it would be appropriate to simply apply Sage's patch to the Debian ipywidgets. I'll try to think of a work-around for us in the meantime.
