[syslog-ng] feature request: clear stats counters after diplayed

I was wondering if it would be possible to clear the stats generated by syslog-ng after theyre logged from the stats_freq setting. Basically so every set of stats that gets displayed will be the numbers since the last time stats were displayed, not for the whole lifetime of the process. Largely, this is just so that one can easily tell if processing has changed in a certain time period without having to do the math. Additionally it also would help a great deal with system health monitoring software. For example, something could look to see if syslog-ng has dropped any messages, but as it currently is it would have to compare the most recent stats with the previous set of stats just to see if the dropped counter went up.
