[boost] [serialization] not so formal review

Hi, Robert. Unfortunately I was not able to look with proper attention onto your submission during review. One thing I did though: all the major issues I mentioned in my original review looks resolved. I am sure will look into more details later, but for now it is enough for me to cast YES vote. This library cover very important problem domain in software development and I think we all have now solid solution. Thanks and congratulation to Robert for being able to bring it to us. Regards, Gennadiy.
