add a jobParam containing platform information. This will be accessible to the siteConfigs so that we can capture the users platform on MASSIVE
alter the platform string a little (don't include architecutre or uname as these have special characters)
forward compatibility for json files to contain properties on teh cmdRegEx which don't exist yet
future proof siteConfigs a little bit, allow the config to contain variables the launcher doesn't understand and allow the commands to contain strings that are not defined if formatFatal=false
