Topic paging

Right now there is no proper paging within a topic itself. On the topic list page, and the forum list page, paging works fine. This is because the advanced_forum_preprocess_advanced_forum_topic_header() method isn't properly initializing paging for the topic itself.

To fix this (Line 446):

// Pager
  pager_default_initialize($variables['node']->comment_count, variable_get('comment_default_per_page_' . $variables['node']->type));
  $variables['pager'] = theme('pager');
