Use Disqus javascript configuration vars to avoid duplicate threads.
For some reason quite a number of our news post entries have resulted in two threads on Disqus side, one with .html extension and one without. This may potentially cause comments to show up in one thread or the other depending on which thread the visiting user is commenting on. Although the reason is yet unkown (it could be a bug from Disqus or some of our users have a whacky browser or feed reader that removes .html extension from our url), the usage of disqus_identifier should solve this issue.
Also setup a new category in the Disqus for all the news post entries' comments. This is in preparation of having more categories later for a new test forum backed by Disqus.
