Fix ft showinfo notebook

[rwedge]

Resubmission of PR #690 so I could avoid making commits directly to the forked repo's master branch.

This fixes #650, where calling featureools.show_info in a jupyter notebook prints the output to the terminal running the notebook instead of printing in the notebook.

I have checked our list of signatories on CLAassistant and confirmed FreshLeaf8865 is on the list. I think the first commit in this PR uses a different email than is recognized by github so it is confusing the CLAassistant.
