Fixed a bug with the previous / next post links.
Fixed a bug with the previous / next post links.

* The prev/next links are not supposed to appear on the home page of
the site, but the $nexPost / $prevPost variables were trying to be set
anyway, which was throwing an error. Fixed by adding a test to make
sure that these variables are only created if you're looking at an
individual node page.
* Also removed stock Drupal commented docs.
