put js in cache (wordtube Version: 2.4.0)

hello
here 2 small improvements easy to include in your next version:
file :statistic.js.php (put js in cache)

header('Content-Type: text/javascript; charset=utf-8', true);
header("Last-Modified: " . gmdate("D, d M Y H:i:s",filemtime(__FILE__)) . " GMT");
header('Cache-Control: public, max-age=29030400');

file : wordtube.class.php (put wordtube in footer)

function integrate_js() {

			wp_enqueue_script('swfobject', WORDTUBE_URLPATH . 'javascript/swfobject.js', false, '2.1');
            wp_enqueue_script('wordtube_stats', get_option ('siteurl') . '/index.php?wordtube-js=true', array('jquery'), '2.0',true);
	}
