Allow 5 "disabled" stars instead of "n/a" when rating==0, and allow "n/a" separately

I would like to be able to display 5 disabled stars instead of "n/a" when the user sets 0 for the value. Obviously these things have different meanings: "i absolutely hated it" vs "i haven't set a rating yet". But personally I'd rather have the confusion and have consistency in my theme instead of showing an ugly "n/a" that confuses users.

This could also be a preference.

As a temporary fix, I just commented out this line of starrating.module (line 236):

  //if ($rate == 0) return t('n/a');

And it enacts the behavior I'm looking for.
