Go to definition does not work for Pandas and other libraries

Issue Type: Bug

Go To Definition does not work for Pandas and any other source type. For example, in this very simple code snippet, i try to CMD+click on a DataFrame symbol and as a seasoned engineer, i expect to go directly to sources of DataFrame class definition, because i have no time to google for documentation nor i generally trust it, because it’s either not that extensive or out of date. And sources have more things to show.

import pandas as pd
pd.DataFrame([{'foo': 1, 'bar': 2}])

navigation does not work also for any module in the sys.path:

import os,sys
# (i have all my exploratory notebooks in `notebooks` folder and my other code in packages up the level)
sys.path.append(os.path.abspath('..'))

this does not work for symbols defined in the same notebook as well:

e.g. def foo(): print(1) in one cell, and foo() in the other cell doesn’t get me jumping the way i’d expect from an IDE.

@nfx. While digging in on this I found a straight up bug here. Basically outgoing links (goto def and whatnot) from inside a notebook file to anything outside a notebook file were not working. I have a fix in progress and should hit the insiders build of the Python extension soonish. Just follow this issue and you should see when it gets closed.
