Improve the way we init the view. The data loader send a "loaded" event, hooked by the scene.py and initializing the backbone.history and the view. We don't use redraw_active in save-once and full-json, because it was making the view initialization dependent of these file which are externals. Small fix to hide the "set saved view" button when there is only one view.

<?php

    require_once(realpath(dirname(__FILE__) . "/../resources/config.php"));

    require_once(LIBRARY_PATH . "/templateFunctions.php");

    $variables = ['config' => $config, 'renkanId' => $_GET['renkanId']];
    $css = [
        'static/lib/renkan/css/renkan.css'
    ];

    renderLayoutWithContentFile("renkan_read.php", $variables, $css);
