merge -r 2158 from branch-1_7 to trunk

fix: in page_header.php U_HOME template var was overwriting the ones from every page -> now it is always make_index_url
fix: unvalidated comments use start end for RSS instead of end only (otherwise google reader creates a new item every time it downloads the feed)
