Fix: Adds support for putting logs in their default locations when logHomeEnabled is false (logHomeEnabled flag was being ignored); Fix: Generating correct sit-cfg overrides when original Log settings aren't set -- e.g. use add sit-cfg verb instead replace (log files would end up in their default location instead of getting overridden); Work-around, if not applying fix: Set 'logHome' to a location that has write-permission.
