Title: checking for image mime-type in NINetworkImageView 

This came up as an issue when pulling nonexistent images from an Amazon s3 bucket, which returns an XML object instead of a 404. This change adds a check to make sure that we got back a valid network image by checking the mime type of the response, which is added as a property to NIOperations.
