Title: Fix the ec2.elb.listener.Listener class's __getitem__ method.

Looks like the indexes were wrong and the ssl_certificate_id was never available this way. I haven't dug through the code to see if there's anything in boto that relies on this behavior, but I have a hard time believing there would be, or this bug would already have been fixed.
