Subject: [PATCH] Add .ipynb_checkpoints to DEFAULT_EXCLUDES (#3293)

Jupyter creates a checkpoint file every single time you create an .ipynb
file, and then it updates the checkpoint file every single time you
manually save your progress for the initial .ipynb. These checkpoints
are stored in a directory named `.ipynb_checkpoints`.
