You shouldn't add target="_blank" to your links, it's deprecated. Users should decide themselves if where they want to open a link.
You can still open the link with unobtrusive JavaScript like so (using jQuery):
$('.container a').click(function(e){e.preventDefault();window.open(this.href);});
That said, you could write your own filter, but you'd have to copy a lot of code from django.utils.html.urlize, not really DRY.
