Non-serializable properties for serializable types

[JechoJekov]

All properties of a type to which the "SerializableAttribute" is applied are intrinsic which is great. However, in some cases serializable types need by extended, for example, to provide an additional property which is a combination of two serializable properties. Therefore, it would be good to be able to mark a property as non-serializable. In this case the compiler should create static getter and/or setter methods similar to what it does for methods of serializable types.
