Move views caching related code to preprocess

This block of code should be moved to the preprocess and reduced to a single print in the template to simplify the template.

      <?php if (!$top_post): ?>
        <?php if (!empty($first_new)): ?>
          <?php print $first_new; ?>
        <?php endif; ?>
        <?php print $new_output; ?>
      <?php endif; ?>
    </div>
