Deduplicate IRC messages
Idea: generate message IDs based on the hash of (author, text, approximate timestamp), where the timestamp can be in increments of say 10 seconds so that if the message is received by two clients during the same 10-seconds timeslice, their id will be the same. Unfortunately in this case dedup will not work at the barriers between 10-seconds timeslices.
