Revert "comment count is displayed incorrectly, reverting"

This reverts commit 091416f33253b6234f32e48073544ee5e6c3e4ff.

A previous commit commented out the count.js call.  Uncommenting/enabling is now reasonable because I've added data-disqus-identifier which lets disqus tell which thread to get data on.
Merge pull request #16 from shaunagm/master
