[boost] [mpl] sequence_wrapper change to handle enums

Would it be OK for me to copy: boost-sandbox/boost/mpl/aux_/sequence_wrapper.hpp to: boost/boost/mpl/aux_/sequence_wrapper.hpp for the reasons cited here: http://aspn.activestate.com/ASPN/Mail/Message/boost/2640803 ? Also, it would also help *nix developers if: boost-sandbox/libs/mpl/preprocessed/preprocess.py were similarly moved. OK to do that?
