Title: Bug fix for django 1.4.1 admin - issue with get_form and adding new records

I was having an issue in django 1.4.1 (presumably also 1.4) when options.py calls get_form when adding a new record, it expects only the `self` and `request` parameters to be required. I defaulted the `obj` parameter to `None` to resolve this.
