syslog plugin: Change notification severity handling.

This way it is more like log severity handling, i.e. "OKAY" implies
"WARNING" and "WARNING" implies "FAILURE".

 Controls which notifications should be sent to syslog. The default behaviour is
-not to send any. If either of C<WARNING> or C<FAILURE> is used, C<OKAY> notifications
-will also be sent to syslog.
-Notifications will be sent using severities based on their own levels. B<OKAY>
-and B<WARNING> will be sent using syslog B<WARNING> severity, whereas B<FAILURE>
-will yield a B<ERROR> syslog entry.
+not to send any. Less severe notifications always imply logging more severe
+notifications: Setting this to B<OKAY> means all notifications will be sent to
+syslog, setting this to B<WARNING> will send B<WARNING> and B<FAILURE>
+notifications but will dismiss B<OKAY> notifications. Setting this option to
+B<FAILURE> will only send failures to syslog.
