This pull request is fully signed and it will be integrated in one of the next CMSSW_5_3_X IBs unless changes or unless it breaks tests. @smuzaffar can you please take care of it?

why add scripts to the data directory?

[vciulli]

Good point.
I added it there because all scripts that are called by ExternalLHEProducer are in this directory, but I don't know why. Most probably for some historical reason (maybe originally there where also tar balls).
However changing the location breaks configurations used for the production.
We will add this point in the todo list but meanwhile it is important to have this pull in for the GEN-SIM production.
