ensuring that $template_body_feed_start and $template_body_feed_end are in the output

In the current version, the markup that is defined as
$template_body_feed_start and $template_body_feed_end is not included
in the output (which prevents Freetile.js from working). This diff
inserts the markup before and after the $template_body_feed_item
section.
