[Building Sakai] Slow forum on sites with large participant list - Sakai CLE 2.8

[Bryan Holladay]

You'll prob find other places you'll want to delete as well.  For instance,
when you delete a forum in processActionDeleteForum you can just set
beforeChangeHM to null and comment out:

SynopticMsgcntrManagerCover.getUserToNewMessagesForForumMap(getSiteId(),
forumId, null);


There are several places where this type of thing is called.  Just comment
out all Synoptic related stuff in DiscussionForumTool.java
