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
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
