cf4c43d344Added Serializer / Deserializer functions for reading & writing matrices. Added bool success parameter to Quaternion::FromLookRotation() and Node::LookAt(), as it can potentially give a NaN result (in which case the original rotation is kept). Optimized reading of math objects in Deserializer to avoid default construction.
