BUG: Fix version conflicts with Jupyter deps

Fixes a problem where Jupyter's require declarations would shadow
Emperor's. Specifically while using the newest version of the Jupyter
notebook jquery would be updated to version 3.x and that version is not
compatible with several dependencies of Emperor.

For now this fix ensures that there will be no version conflicts by
putting all our dependencies under their own context.
