Subject: [PATCH] boost::filesystem cross-platform config file check

* introduces the use of the Boost.System and Boost.Filesystem libraries,
  which must be built and linked to rather than just compiled into
  OpenMW. May be a pain in the neck to get working on other platforms,
  but once it works, we have all of Boost to work with.
