Setup fails on windows

[Olwaro]

On my Windows system : pip install humanize (or python setup.py install on sources) fails with this error :
UnicodeDecodeError: 'charmap' codec can't decode byte 0x81 in position 2017: character maps to <undefined>
Full stack trace here

I have naively fixed that by replacing this line by :
long_description=open('README.rst', 'r', encoding='UTF8').read(),
I don't know if it's a great solution but it worked for me.

I get this error as well on Python 3 on Windows.
It would be nice if this could be fixed quickly. It would be messy to expect users to install fixed forks of humanize.

Could you release the fixed version on PyPi? Our project is depending on humanize and we would like to support Python 3.

New version released as it may be the last version before an extra external dep.
