- 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
