Added a stripped down MPI version of standalone: standalone_mpi. In fact, it's more like a pure simulation module since I've dropped real-time rendering and other old parts that do not work with MPI without heavy modifications. The most important functionalities in addition to simulation have already been adapted to work with MPI (samples/benchmark and samples/mpi) so there's no need to re-create them in standalone_mpi. The current version of standalone_mpi is able to run a basic simulation and I get an agreement with non-mpi and mpi versions after 100 timesteps. There's also draft that's a direct adaptation of what's currently in standalone/simulation.cc (it should be 100% equivalent), but it's currently commented out as I haven't done extensive tests with it.
