Make the event_log update more than one line per minute

[PaulHancock]

The event_log only updates 1 line per minute.
As a result, the event log on the website can occasionally get behind. I've seen it be 20 mins behind, but later was able to catch up.
Recommend we update the twisted_comet_wrapper.py to poll the output of the twisted log more often (5sec)

[PaulHancock]

Also recommend that we have more verbose logs (use -v -v to include debug msg).
Based on 3 days of logs from the OG mwa system, we would be receiving a message every 10s on average, so a 5 sec poll time would work.
