Win-unicode-console

---

- Recovering of Unicode ``sys.argv`` on Python 2 is now supported: module ``unicode_argv`` was added. Fixes 20.
- The runner uses ``compile(..., dont_inherit=True)`` even on Python 2. Fixes 14.
- Console detection was enhanced: ``StandardStreamInfo`` objects with methods ``is_a_TTY``, ``is_a_console``, ``should_be_fixed`` in ``streams`` module. ``sys.std*`` streams without ``fileno`` (e.g. Python 2 ``StringIO``) are supported.
- Custom readline hook is disabled on error to avoid an infinite loop in interactive session.

---

- Python 2 is now supported. Fixes 7.
- The ``runner`` package and ``run`` script were enhanced. Since custom REPL is not needed, it is not used by default, and the runner serves as a way to execute initialization code before running a main script. There are more options for the an initialization code, see the readme file or ``run`` script help.
- The package can be now imported on Unix and other platforms. The top-level ``enable`` function does nothing on platforms other than Windows. Fixes 8.
- The signature of ``streams.enable`` was changed. ``streams.enable_only`` function was added. The functions ``enable_reader``, ``enable_writer``, and ``enable_error_writer`` in ``streams`` module were removed.
- When ``sys.stdin.encoding != sys.stdout.encodin``, ``RuntimeWarning`` is raised by ``readline_hook`` module rather than ``ValueError``.
- The readme file was mostly rewritten.
- A changelog file was added.

-----

- Changed the loader of msvcrt library from windll to cdll. Solved 5.

---

- Added possibility to set custom readline hook. Also ``pyreadline`` hook can be reused. Custom REPL is no longer needed.
- Added transcoding wrappers to streams, since there is a problem with UTF-16 encoding.
- New interface ``win_unicode_console.enable``, ``.disable``.
- Stream objects have standard filenos now, custom readline hook is needed for ``input()``.

---

- Better treatment of reading zero or one bytes so infinite loops aren't started on higher levels.
- Added automatical flushing in REPL.
- Interaction with Python object to read and write bytes now uses buffer protocol.
- Changed type of read/written bytes variable from c_long to c_ulong to be compatible with pyreadlines and the specification, which says DWORD. Solves 2.

-----

- Added ``__init__.py`` for better compatibility, see issue 1.
