A method for overriding default raw_id_fields behavior

[damon c]

The default behavior for the modelAdmin is to render a <select> element containing every instance of the model referred to by the FK.  

When this field refers to a model that has for example, 100,000 or more entries, this can have the affect of crashing a server, a browser, or at best making new users confused about why they cannot view the admin page for this instance as they will often experience a timeout.

I was thinking something like the following on admin.BaseModelAdmin might be helpful for people who would like to implement a different default behavior.

def get_raw_id_fields(self):

    """

    Hook for overriding default raw_id_fields behavior

    """

    return self.raw_id_fields

Anyone think this might a good idea?
