added raw_id_fields to EventProcessingException admin
ensure all boolean fields have False as default, otherwise in Django 1.6 it will be None
Add send_receipt option to Customer.charge
Only update the card if there is such data

to let user subscribe to free plans without credit card infos
Add support for Django 1.6

Three changes required:

 - BooleanField no longer defaults to False
 - filter(date__month=..., date__day=...) is now timezone aware, so
   a timezone needs to be specified in the settings
 - it now seems to require pytz, probably because of timezone
   awareness
