D6 og_access_roles php 5.4+ warning declaration views handler field pre_render

This may be important for some people with the ongoing efforts in the Drupal 6 LTS project. When using this module and php 5.4, 5.5, 5.6 and 7.2 a warning declaration notice occurs

warning: Declaration of og_access_roles_handler_field_rid::pre_render($values) should be compatible with views_handler_field::pre_render(&$values) in /sites/all/modules/og_access_roles/includes/views/handlers/og_access_roles_handler_field_rid.inc

Patch to follow.
