don't automatically add jobarray or queue lines to user template In parallel launchers, the queue and jobarray lines should not be added except in the default templates. user-templates must be fully specified. This prevents conflicts between PBS versions, which may not support jobarrays, etc. These lines are now only added to the *default* templates.
