resolveNode

Implementers should accept instances of NodeReference (a.k.a. SerializedNodeReference) and deserialize them into supported references if possible. This removes the need to register an INodeReferenceSerializer and also postpones the deserialization until it's actually necessary.

For backwards compatability reasons this method should not be called directly, but INodeReference.resolveIn should be used, which tries to deserialize the reference first, in case an implementation of this method doesn't do the deserialization itself yet.
