Title: fixed detach_network_interfaces() to accept an AttachmentId

EC2 API calls for an AttachmentId when detaching an elastic network interface:
http://docs.amazonwebservices.com/AWSEC2/latest/APIReference/ApiReference-query-DetachNetworkInterface.html

This changes the call on boto.ec2.EC2Connection.detach_network_interface to reference AttachmentId instead of NetworkInterfaceId
