[boost] Requests for changes in 1.33 related to serialization

I want to suggest 2 changes that would be helpful at least to me, that relate to serialization. I use serialization with mersenne_twister and python. To support this 2 changes are needed: 1) serialization must be build as a shared library. I know this doesn't work on all platforms, but I believe it works on at least some, and therefore should be supported. 2) Please add support for serialization to mersenne_twister.hpp. All that's needed is this: template<class Archive> void serialize(Archive & ar, const unsigned int version) { ar & x; ar & i; }
