Python 3.2 not supported

[MickaelBergem]

Hello,

I noticed (in production, too bad ^^) that django-notification was not compatible with Python 3 before Python3.3, because get_ident from the threading module is new in Python3.3 (https://docs.python.org/3/library/threading.html#threading.get_ident).

I don't know where to put this kind of requirements in the documentation / README, where should we put it ?

Django/Python requirements are addressed in the recent update supporting Django 2.0
