add app_name to urls.py

If we add the app name newsletter, then the path names should not be prefixed with newsletter.

So newsletter_subscribe_request should become newsletter:subscribe_request

This would break backwards compatibility BTW but I think its a necessary change if we are going to add app_name.

Actually, this is already a breaking change because, for example, the Newsletter method already does not work:

    def update_url(self):
        return reverse('newsletter_update_request', kwargs={'newsletter_slug': self.slug})

It should be changed to newsletter:newsletter_update_request. Then it would be better that it becomes just newsletter:update_request

Can you please update all path names to remove the prefix, and also update all references to these paths?
