* fix confused flake
We run `black --target-version py35 ...` but flake8 doesn't know that, so currently with py38 flake8 fails suggesting that black should have reformatted 63 files. Indeed if I run:
```
black --line-length 119 --target-version py38 examples templates tests src utils
```
it indeed reformats 63 files.
The only solution I found is to create a black config file as explained at https://github.com/psf/black#configuration-format, which is what this PR adds.
Now flake8 knows that py35 is the standard and no longer gets confused regardless of the user's python version.
* adjust the other files that will now rely on black's config file
* Copy code from Bert to Roberta and add safeguard script
* Fix docstring
* Comment code
* Formatting
* Update src/transformers/modeling_roberta.py

This prevents transformers from being importable simply because the CWD
is the root of the git repository, while not being importable from other
directories. That led to inconsistent behavior, especially in examples.
Once you fetch this commit, in your dev environment, you must run:
$ pip uninstall transformers
$ pip install -e .
