Problem when automatically rendering form-control-static

[massawho]

Hello, I am new using django-bootstrap3 and it's a nice project. Thank you.
I am entirely replacing the django admin template and found that django-bootstrap3 does not render form-control-static automatically. I found this issue when I replace the form template and saw that the password widget (on user edition page) had a line over the text that says the algorithm, iterations, ,etc.

I managed to workaround the problem, but not sure if it is the best solution, since it will not work for any other widget outside the django-admin that needs to render a div instead of input or something.

Here is my new add_class_attrs function on renderers.py (from line 201)

def add_class_attrs(self):
    classes = self.widget.attrs.get('class', '')
    if isinstance(self.widget, ReadOnlyPasswordHashWidget):
        classes = add_css_class(classes, 'form-control-static', prepend=True)
    else:
        if not isinstance(self.widget, (CheckboxInput,
                                        RadioSelect,
                                        CheckboxSelectMultiple,
                                        FileInput)):
            classes = add_css_class(classes, 'form-control', prepend=True)
            # For these widget types, add the size class here
            classes = add_css_class(classes, self.get_size_class())
    self.widget.attrs['class'] = classes

ReadOnlyPasswordHashWidget is from django.contrib.auth.forms, so it would be nice to take that into account. It fits the "it should be both Django and Bootstrap" rule.

Any feedback on this from other users?
