[nobm] improve lauX.sh script, add support for a generic process #683

(This is the result of cherry-picking ce995d8 and fixing conflicts)

The syntax for launching has now changed - must add the trailing .mad
CUDA_HOME=none HRDCOD=1 tlau/lauX.sh -CPP nobm_pp_ttW.mad

This now fails with the usual three IEEE FPEs (all except division by zero)
