Print timer only on ROOT MPI process.
Bug fix: Do not free MDCORE_neighb_ array since it is only a pointer to the LAMMPS neighbor list. This lead to nasty segfaults.
Merge branch 'master' of github.com:pastewka/mdcore
Removed REV revision file.
Autodetect mpi include path (from path to mpicc). Also remove -check bounds debug option because it will always fail with LAMMPS. (LAMMPS uses strides to allocate the neighbor list. If more than one stride is used it will be reported as out-of-bounds, although the memory location is okay.)
