- allow template class to be instantiated with an empty theme (in plugins for example)

- local_head must now be defined in the themeconf.inc.php otherwise not taken into account (avoid several calls to file_exists)
- renamed themeconf['theme'] to themeconf['name'] (this is what it is themeconf[theme] is confusing)
