Form validation is bypassed on Admin Inline ModelForms that define extra fields

When defining extra/overridden fields on modelforms, validation is bypassed. This can lead to errors under some circumstances.
For example, you have a model 'Book' that defines a ForeignKey to 'Author' named 'author'. On your ModelForm you replace this field by a CharField (or some other type) for whatever reason.
On submitting an invalid form, a ValueError will be raised complaining that the datatype is incorrect.
My proposed solution is overriding ModelForm._post_clean():
class ModelForm(BaseModelForm): def _post_clean(self): if len(self._errors) == 0: super(ModelForm, self)._post_clean()
