Deprecated openmpi 2.0.2-gcc module

We identified a problem with the openmpi/2.0.2-gcc module and have removed it as the correct interface was not being used for the MPI communication between nodes. This resulted in potentially much slower communication and consequently jobs taking longer to run.

Programs should be rebuilt against the other available openmpi modules which correctly select the Infiniband interconnect as default for communication. Recent users of this module have been contacted directly.
