Patch Notes: No more dawn slowdown in big cities

Fixed

Big cities no longer drop to a frame or two a second between 4 and 6 in the morning (game time). Every time the game looked at a city watchman who sets out for their post before the day begins, it worked out the whole town's day again from scratch - hundreds of townspeople, every frame. It was worst in the great cities, Daggerfall among them; offline the slowdown kept itself going, and online it came back with every in-game dawn. The people on the street are exactly where they were before.
A port whose harbour lies far from any street no longer searches for its dock four times a second.

LW-DAWN: a day's cache keeps the day beside it - the living town re-planned itself every frame from 04:00 to 06:00 by @Lattymoy in #663
