Users can now publish directly to Facebook

We have expanded the functionality of our integration with Facebook. First, and most importantly, we have stopped using the deprecated Facebook Connect platform, and instead switched over to the new Graph API. This change includes rendering Open Graph metadata on each page, which is used to semantically describe certain content like threads, blog posts and CMS articles. On top of this, we have implemented automatic posting to a user's newsfeed/wall for the following items:

1. New threads
2. Thread Replies
3. Blog Entries
4. Blog Comments
5. New CMS Articles
6. Article Comments

Also, we have added the "Like" button for threads, blog entries and articles.
