Update py to 1.8.2

[pyup-bot]

This PR updates py from 1.5.3 to 1.8.2.

Changelog

1.8.2

==================

- On Windows, ``py.path.local``s which differ only in case now have the same
Python hash value. Previously, such paths were considered equal but had
different hashes, which is not allowed and breaks the assumptions made by
dicts, sets and other users of hashes.

1.8.1

==================

- Handle ``FileNotFoundError`` when trying to import pathlib in ``path.common``
on Python 3.4 (207).

- ``py.path.local.samefile`` now works correctly in Python 3 on Windows when dealing with symlinks.

1.8.0

==================

- add ``"importlib"`` pyimport mode for python3.5+, allowing unimportable test suites
to contain identically named modules.

- fix ``LocalPath.as_cwd()`` not calling ``os.chdir()`` with ``None``, when
being invoked from a non-existing directory.

1.7.0

==================

- fix 174: use ``shutil.get_terminal_size()`` in Python 3.3+ to determine the size of the
terminal, which produces more accurate results than the previous method.

- fix pytest-dev/pytest2042: introduce new ``PY_IGNORE_IMPORTMISMATCH`` environment variable
that suppresses ``ImportMismatchError`` exceptions when set to ``1``.

1.6.0

==================

- add ``TerminalWriter.width_of_current_line`` (i18n version of
``TerminalWriter.chars_on_current_line``), a read-only property
that tracks how wide the current line is, attempting to take
into account international characters in the calculation.

1.5.4

==================

- fix pytest-dev/pytest3451: don't make assumptions about fs case sensitivity
in ``make_numbered_dir``.
