FastRetinaKeypointDetector should be marked as serialiable

[GoogleCodeExporter]

Creating a bag of visual words for FREAK makes it impossible to save it, since 
the FastRetianKeypointDetector is not marked serializable.

// The following example raises a SerializationExample.
FastCornersDetector fast = new FastCornersDetector();
FastRetinaKeypointDetector freak = new FastRetinaKeypointDetector(fast);

var kmodes = new KModes<byte[]>(32, Distance.BitwiseHamming);
var bagOfVisualWords = new BagOfVisualWords<FastRetinaKeypoint, byte[]>(freak, 
kmodes);

using (FileStream stream = new FileStream("bag-of-visual-words", 
FileMode.Create))
{
    bagOfVisualWords.Save(stream);
}

Should of course be a SerializationException.

Should be fixed in the 2.11 release.
