Deprecate old npm repos

[jasongrout]

We should deprecate these on npm and put a note in the package.json description that they have been superseded by the jupyterlab package:

• jupyter-js-notebook
• jupyter-js-docmanager
• jupyter-js-domutils
• jupyter-js-terminal
• jupyter-js-filebrowser
• jupyter-js-ui
• jupyter-js-plugins

We should also note in the github repos that the repos have been superseded by the jupyterlab repo. We should probably move the repos to some jupyter-attic github org.

I think this covers all of the bases:

• move the repo to the jupyter-attic org
• Update each one-line repo description on github to say "Deprecated"
• Update the readme files to point to the new repo
• update the package.json description so the deprecation shows up in npm
• update the package.json repo to point to the jupyter-attic location
• use the npm deprecation command to officially deprecate the repo

This is done!

[jasongrout]

Nope, not done! The npm package needs to be deprecated...

@jasongrout is this still relevant - did you finish it?

[jasongrout]

Not yet. Probably still relevant - just need some time for the woodcutting, as @SylvainCorlay would say.

[jasongrout]
