Greatly decreases the number of objects that need to be created (currently 3 event handlers in total vs basically 3 per datum)
The price is a slower lookup of listeners but on a per round basis it should still be much less than the current startup time penalty.
Corrects a number of places where New() did not call ..(), and implements similar changes to attempt to ensure New()/initialize() complete running before qdel() runs.
Cuts down on the number of created items during server start.
