Title: updated Field inheritance pull

I updated the code from shelldweller's pull request #40 and merged it into my branch from the trunk (1st commit).

I also added a new test (with supporting model/fields) to verify that custom fields which inherit from `models.Field` are not filtered by default, but are when included by setting `filter_overrides` on the `FilterSet` (2nd commit).
