Commit Description:
Optimize PreserveCounts and only recalculate when needed. Previously would recalculate preservecounts every Update call (~1 per frame), which isn't necessary when there's no tick. Might be some room to tweak, like doing these updates only when preserves change. Some measurements: This takes about 30ms versus the .25 ms with no preserve (then like .0002ms). When the map is filled up with preserve, about 35ms and 9ms. With a handful of cells, it's more like 0.8ms (before JIT optimizes most of it away).
