Cucco v2.2.0

Cucco is back with a minor release.

This version fixes issue #42, adding the possibility to normalize a single file using cucco CLI. The library itself has suffered an small change too. Normalization function 'remove_extra_whitespaces' has been renamed to 'remove_extra_white_spaces'. This means that any previous code or config file using this function will break if using the last version. Sorry for that 😞

Happy normalization 🐔
