Add batch submission script for the NAF (DESY)
Merge pull request #133 from DESY-CMS-SUS/NAFbatchForCMG

Merging. Next time however please try to keep the diffs cleaner by not changing the whitespace in the files you modify (or use git add --interactive to just commit the hunk of lines that you really changed skipping the others where you only modified the whitespace, and then reset the file to bring the original whitespace back)
Merge with CMG_central. Includes latest updates for the NAF batch submission script
