Made the variable for disabling the logging system always default to ON instead of OFF. Changed the wording so it's less confusing.

This means that the debug logging information will not display at all by default, but the GM command logging will display enabled. If you need to diagnose the logs, simply turn them on at the expense of added CPU/Disk I/O
