A login_required decorator that wraps the login view instead of redirecting to it.
This prevents your site from leaking login information with HTTP status codes as explained here.
This is the way Django's admin is protected, the difference being that it checks for is_active and is_staff instead of is_authenticated.
With this decorators, users directly see a login form (no redirect), post it to LOGIN_URL and are redirected to the page they first tried to see.
