only show wiki options for a content type if og_access module is enabled. folks are now encouraged to try out the new content type selector at the bottom of the content type edit form. you can now safely designate a content type as a wiki, similar to what you may have seen on groups.drupal.org.

See the new 'content types' fieldset on the admin/og/og page ... Requires a visit to update.php which will rebuild your node access table. I have a little code shuffling to do still so you might want to wait until next commit before trying this. Also implements #111836 which changed how we do node access grants.
