Connect the Notebook to the Variable Explorer

[ccordoba12]

The idea is to add to NotebookClient a hidden IPython ShellWidget and connect that shell to the VariableExplorer.

For this we need to detect:

1. When a kernel is ready to receive commands.
2. When a cell has finished execution.

@goanpeca, we need your help for this one :-)

Any progress on this feature? Wondering in light of the news about funding... This one feature would keep me using Spyder for the foreseeable future, so I'm really interested in seeing how it's been going/how easy it would be for you guys to put in.

Please consider donating if you want to see this implemented because it's not an easy task.

I see. Unfortunately I'm a student at the time and not in a position to do so - that's a pity. Thank you for your continued effort on the project as a whole!

Any continuing interest in this task? I would totally donate to help this along.

Yes @egtwobits but we need hands and help!
