bug fixes

* Display comment count in blog post (admin and front-end).
* In admin, also display # of pending comments.
* In admin, both comment count and pending count are hyperlinks to the "manage comments" page for the blog post.
* Fix a few incorrect redirect calls in the comments module
* Removed fake comment count display for aggregate blog view (we will resurrect it later with a correct implementation)
