Rewrite of core code

Sends all requests as a single update vs multiple individual updates With a server with a LOT of queues, and 6 items per queue, that meant (previously) as many as over 1000 sends a minute. With the new approach (thanks to https://github.com/zentavr/), we now can publish all the results at once. This not only reduces the CPU costs of checking, but is a far more efficient approach overall.

Message rates per server and per queue now available. This includes graphs displaying these results. This is being tracked for every queue, as well as the server itself.
