Small footer edit

I've added foreach for js, this eliminate unnecessary retyping:

	<script src="/js/plugin/my_blabla_plugin.js"></script>

in controller we can use this:

	$data['js'] =  array(
		'http://mysite.com/a.js',
		'http://mysite.com/b.js',
		'http://mysite.com/c.js',
		'http://mysite.com/d.js',
	);

or 

	$data['js'] =  array(
		DIR . 'js/main.js',
		\helpers\url::get_template_path() . 'js/test.js',
	);
