Make tests pass on Windows too

Windows Pythons seem to like printing addresses in upper-case, while Linux
Pythons like lower-case hexes.

This led to an amusing (for a given value of "amusing", anyway) situation
where some repr tests would fail if the objects they were testing happened
to be allocated at an address with a hex digit in the range A..F.

This re-stabilizes sorting after upgrading to 4.2.2.

This gets rid of a file encoding bug that occurs on Windows boxes where
the default implied encoding is cp1252, but the files themselves aren't.

The actual patch that seems to fix this is
https://github.com/timothycrosley/isort/commit/1057d5e12edbb3030045b7a7a8c82f0848635fef
but it seems like a good idea to upgrade to the latest and greatest.

Version 0.11b3's setup.py had an undeclared dependency on `py2exe` when
running on Windows (see
https://github.com/transifex/transifex-client/blob/0.11b3/setup.py#L23),
which made it impossible to install without having a working `py2exe` to
begin with.

This has been fixed in 0.11 proper.
