Pydocstyle

Bug Fixes
- Fixed an issue where the `flake8-docstrings` failed when accessing some public API from `pydocstyle`.

Major Updates
- pydocstyle is no longer a single file. This might make it difficult for some users to just add it to their project, but the project has reached certain complexity where splitting it into modules was necessary (200).

New Features
- Added the optional error codes D212 and D213, for checking whether the summary of a multi-line docstring starts at the first line, respectively at the second line (174).
- Added D404 - First word of the docstring should not be “This”. It is turned off by default (183).
- Added the ability to ignore specific function and method docstrings with inline comments:
“ noqa” skips all checks.
“ noqa: D102,D203” can be used to skip specific checks.

Bug Fixes
- Fixed an issue where file paths were printed in lower case (179, 181).
- The error code D300 is now also being reported if a docstring has uppercase literals (R or U) as prefix (176).
- Fixed a bug where an **all** error was reported when **all** was imported from another module with a different name (182, 187).
- Fixed a bug where raise X from Y syntax caused pydocstyle to crash (196, 200).

New Features
- Added the D104 error code - "Missing docstring in public package". This new
error is turned on by default. Missing docstring in `__init__.py` files which
previously resulted in D100 errors ("Missing docstring in public module")
will now result in D104 (105, 127).
- Added the D105 error code - "Missing docstring in magic method'. This new
error is turned on by default. Missing docstrings in magic method which
previously resulted in D102 error ("Missing docstring in public method")
will now result in D105. Note that exceptions to this rule are variadic
magic methods - specifically `__init__`, `__call__` and `__new__`, which
will be considered non-magic and missing docstrings in them will result
in D102 (60, 139).
- Support the option to exclude all error codes. Running pep257 with
`--select=` (or `select=` in the configuration file) will exclude all errors
which could then be added one by one using `add-select`. Useful for projects
new to pep257 (132, 135).
- Added check D211: No blank lines allowed before class docstring. This change
is a result of a change to the official PEP257 convention. Therefore, D211
will now be checked by default instead of D203, which required a single
blank line before a class docstring (137).
- Configuration files are now handled correctly. The closer a configuration file
is to a checked file the more it matters.
Configuration files no longer support `explain`, `source`, `debug`,
`verbose` or `count` (133).

Bug Fixes
- On Python 2.x, D302 ("Use u""" for Unicode docstrings") is not reported
if `unicode_literals` is imported from `__future__` (113, 134).
- Fixed a bug where there was no executable for `pep257` on Windows (73,
136).

New Features
- Added support for more flexible error selections using `--ignore`,
`--select`, `--convention`, `--add-ignore` and `--add-select`
(96, 123).

Bug Fixes
- Property setter and deleter methods are now treated as private and do not
require docstrings separate from the main property method (69, 107).
- Fixed an issue where pep257 did not accept docstrings that are both
unicode and raw in Python 2.x (116, 119).
- Fixed an issue where Python 3.x files with Unicode encodings were
not read correctly (118).
