Rend GestioCOF compatible avec python 3. En particulier, il s'agit de :
- Utiliser la version "fonction" de `print` dans `sync_clipper` et
`tirage_bda`, avec le `from __future__ import print_function` pour
garder la compatibilité avec python 2
- Utiliser de l'unicode par défaut, même en python 2, avec
`from __future__ import unicode_literals` et le décorateur de
compatibilité `python_2_unicode_compatible` de Django pour les
modèles, comme décrit à
https://docs.djangoproject.com/en/1.9/topics/python3/#str-and-unicode-methods
- Utiliser `six.text_type` à la place de `unicode`
Fixes #2.
