References original_content_type_id, removed in Django 1.10

[maxb]

Current code still mentions original_content_type_id in the templates... however:

RemovedInDjango110Warning: InlineAdminForm.original_content_type_id is deprecated and will be removed in Django 1.10.
If you were using this attribute to construct the "view on site" URL, use the absolute_url attribute instead.
