* Change default LogLevel to None which means "unset"

Logger.getGlobalLevel then returns LogLevel.Warn when the current value
is LogLevel.None. This preserves the behavior of the default being
"Warn" but now uses LogLevel.None to indicate "I'm not setting the
value." This resolves issues where it was not possible to tell if
annotations were actually setting the log level or if the default level
of warn was just being filled in.
