Proximity distance field does not hide distances that are 0.00

I changed list 62 of openlayers_proximity_handler_field.inc

from:

    // Check to see if hiding should happen before adding prefix and suffix.
    if ($this->options['hide_empty'] && empty($value) && ($value !== 0 || $this->options['empty_zero'])) {
      return '';
    }

to:

    // Check to see if hiding should happen before adding prefix and suffix.
    if ($this->options['hide_empty'] && ($value == 0) && ($value !== 0 || $this->options['empty_zero'])) {
      return '';
    }
