Support Internationalization (i18n) for menu translation in superfish implementation

Internationalization (i18n) comes with a sub module for menu translation which works fine with regular menus and even superfish menus generated by the superfish module (just tested it).

However this theme hardcodes embedded support for superfish menu in its main menu at the top of the page and does not use i18n API for rendering language specific menus on multi-language sites.

I took a look into both the theme's page.tpl.php and into superfish.module and gave it a short try, but I'm not familiar with the module, so it would take a bit longer. Maybe someone or the theme's developer will be more efficient at making what I'm sure is a simple change (passing the menu rendering through i18n's API or even simpler through the superfish.module which already does it).

This is the actual code in the theme's
/sites/all/themes/likable/templates/page.tpl.php

            <div id="main-menu">
                <?php 
              $main_menu_tree = menu_tree(variable_get('menu_main_links_source', 'main-menu'));
              print drupal_render($main_menu_tree);
            ?>
            </div>

This is the code on superfish.module that actually passes the menu rendering through i18n's filtering:

    $cache = array();
    $cache['menu'] = menu_tree_all_data($menu_name);

    if (module_exists('i18n_menu')) {
      $cache['menu'] = i18n_menu_localize_tree($cache['menu']);
    }
