Finalize 0.1.0

We're going unicode folks! It deserves to be the first minor version.

The values returned from `i_get_csv_data` will be `unicode` instead of `str`.
Meaning it supports all the data encodings. If any of your code expects the
values to be str, please revise to expect unicode.

You may also now write data as csv outside the ascii charset. Away UnicodeDecodeError and UnicodeEncodeError!
