Added ESPResSo for both serial and parallel style of execution

Despite that this one seems to run, eventually more work on this one might be required,
mainly because the goalf stack might not be the optimal match for this code.
It may turn out that a better toolchain for this one may be ictce or gmvapich2.

Anyhow, this is the processed form of what I have received from Josh
and if he doesn't bring up any issue I consider it production...
