- Fixed activity links to blog comments regardless of preferred sort order.  Making this fix on paginated forum threads is considerably more complicated, so may take quite a while.

- Library fix for publication date sort

- Added threaded comments for blogs, so you can add a comment as a reply to another comment.  We don't really have a design for the reply comments yet, so bear with us there.  Also, this feature should be considered beta for now, but hopefully it will help.  Again, considerably more complicated to implement for forum threads.
