title: Getting `django-registration` to send you to the page you were originally trying to visit
body: <p><code>django.contrib.auth</code> has an awesome feature: When you try to access a page that's decorated by <code>login_required</code>, you get redirected to the login page with a <code>next</code> argument, so after you login you get redirected back to the page you were originally trying to access. That's good for the user flow.</p>
  
  <p><strong>But,</strong> apparently <code>django-registration</code> does not provide a similar feature. I expected that if you register instead of login, you would also get a <code>next</code> thing, and after registering-n'-activating you'll get redirected to the page you were originally trying to visit. This is not the case, you're just redirected to some success page. This hurts the flow.</p>
  
  <p>Does <code>django-registration</code> perhaps provide this option but I'm not using it or correctly? Or is there an easy way to do this?</p>
