Commit 53b4518 made added explicit utf-8 encoding for all sources, among
other things. A copyright notice in `tests/test_tr.py` was removed and
two were added in `num2words/lang_it.py`. I know this was a simple
mistake, I just thought it would be best to explicitly give credit where
credit is due.
Some maintainers for different linux distribution are having some
problems with the encoding on different python versions. This change
intents to make all python files define explicitly the encoding, license
and unix line separators. Remove one example of the README.rst file
where a possible non UTF-8 character is used.
* Activate flake8, isort and coveralls in the configuration of tox
* Update code to respect PEP8
* Fix bug in the lang_IT for python 3
* Update the README to include the new converters.
