Subject: - fix typing error in index.tpl - added template smarty function
 known_script (e.g.{known_script id="x" src"y.js"}) - useful to avoid double
 inclusion of a script such as prototype,jquery,... when a template and plugin
 need it independently (see the use in admin.tpl for example) - removed unused
 themeconf.template_dir
