Keeps the boost libraries up to date. This also silences informational messages that get spammed throughout the build, such as: "Info: Boost.Config is older than your compiler version - probably nothing bad will happen - but you may wish to look for an update Boost version. Define BOOST_CONFIG_SUPPRESS_OUTDATED_MESSAGE to suppress this message." Which makes the compilation process a lot less noisy on Windows. It's now much easier to actually spot warnings that occur.
