Fix default log level NOTSET

[mkcn]

The current default level for logs is NOTSET.
The goal was to disable logs with this, but due to a incorrect interpretation of the value we now have log enabled in full mode by default.

Need to replace this:
# log options: NOTSET > CRITICAL > ERROR > WARNING > INFO > DEBUG
with:
# log options: NONE, CRITICAL, ERROR, WARNING, INFO, DEBUG
# note: in DEBUG mode the size of your log file may grow rapidly
where NONE = 60
