Include *.ipynb files and only *.md files

[francoisschwarzentruber]

Problem

I want to be able to include *.ipynb files (Jupyter notebook files) in my book. The problem is that mdbook does not recognize these files. We could circonvent this problem by first convert the *.ipynb files into *.md but this is tedious.

Proposed Solution

Being able to include *.ipynb files for free!
