Title: Add BigIntegerField to the Django model types supported for IntegerField...

Regarding issue:
https://github.com/toastdriven/django-tastypie/issues/760

The Django model BigIntegerField is missing from the list of fields for IntegerField in Resource.api_field_from_django_field() so it defaults to a CharField.
