as promised : first update

a commit as short as possible : 3 files affected.
backward incompatibility fixed.

next commit : only "django.po" and ".mo" (generate with couple makemessages/compilemessages)

precision: this commit (and futures) will respect "good" unix permissions (755 to dir and 644 to files).

one doubt :

this repo works on python >= 2.6? For 2.5, you must use django.contrib.localfalvor.fr, right? (explacilly "from __future__ import unicode_literals" don't exist on python 2.5)
Why using "from __future__ import absolute_import" if "absolute import" works on python >= 2.6?
