Subject: [PATCH] [#731 state:resolved] SCHEMA VERSION BUMP - UPGRADE AHEAD! 
 Restored mt_comment_blog_ip_date index which, before it's removal, was
 critical in streamlining performance of the comment app when comment
 throttling is enabled.  Also removed mt_comment_parent_id index which was
 redundant and also removed from MT 5 for performance reasons.
