Make OG breadcrumbs disableable

There should be an option to turn of OG breadcrumbs so that posts that belong to a group can still use normal Drupal breadcrumbs if they are placed in the menu tree. After searching for a solution I found a site with a solution (http://www.aidanfindlater.com/2008/11/10/drupals-organic-groups-messing-...) but it requires hacking the module.

The only change necessary is to switch og_get_breadcrumb in og.module to drupal_get_breadcrumb(), but there should be something built in to make this an option (if not the default).
