Added a heading "editing page" in page editor for visual appeal; removed use of alternate <?= ?> syntax in installer as it was causing problems on Win2k3 + PHP/FastCGI. (Experimentally using TortoiseHG's hgtk to commit)

<?php

class Text_Wiki_Render_Plain_Newline extends Text_Wiki_Render {
    
    
    function token($options)
    {
        return "\n";
    }
}

?>
