Title: Speed Enhancement from Mike Ryan

While troubleshooting a problem, Mike Ryan and I discovered that a number of extra calls were being made to the map function within packet_prefixes, slowing down the execution of packet reads. This patch will only update the map when something changes, reducing a large number of map calls over the course of a script execution.
