Merge branch 'Elarnon/unicodecsv' into 'master'

Utilise unicodecsv de PyPy

GestioCOF utilisait une implémentation locale du module `csv` compatible
avec `unicode`. Il existe un module PyPy du même nom qui fait la même
chose, autant l'utiliser (par ailleurs, il fonctionne plus sainement
avec Python 3).
