* Add --docstring-convention option which allows selection of conventions
besides the default pep257. Available options are based on those
available from pydocstyle and are currently pep257, google, and
numpy. flake8-docstrings also adds a special all docstring
convention which will enable all rules from pydocstyle. Note that
pydocstyle defines some conflicting rules so you'll want to use
ignore / extend-ignore when selecting docstring-convention = all
* Bump minimum flake8 version to 3
* Fix proper handling of stdin via --stdin-display-name
