Boost 1.34.1 released

Boost 1.34.1 has been just released. Compiles to 2.52 GiB of binaries on x64, and rougly 1.8 GiB of binaries on x86. Initial compatibility tests look good here, so I can only follow the recommendation to upgrade to Boost 1.34.1 if you are using Boost 1.34.0. However, the boost headers that were copied into the x64 install target were not complete so I had to use the x86 install for the headers.
