compare runNmb in csv and args as ints

This allows when using the "--zfill" option to not necessarily have all the leading zeros in the csv file

When using the "--zfill " option the "@RunNumber@" in the template config files gets zero filled until n digits. So far when using the jobsub tool one would specify the run numbers on the command line as numbers / int (no leading zeros necessary) In the csv file (given with the "--csv <runs.csv>" parameter) the run numbers had to have these leading zeros. Otherwise no config file was generated and jobsub would simply state "Problems with submission"
