Updates the Field Item Editor to render layers based on the entire map, and the per-patch positioning of each layer.
Import/export will gracefully handle upgrade/downgrade, and viewport import/export will gracefully update tiles rather than a per-acre basis.
Performance has also been slightly improved; no allocation is done anymore when updating the image.
Adds data for supporting 3.0.0, still needs savefile structures/hash range dumped and incorporated into MainOffsets30/PersonalOffsets30. Offsets/range is currently a copy of 2.0, which is obviously not correct. Saves will fail to load as encrypted values are not at the expected offset (pls no complaints).
CTRL-I from main form still opens the injector interface; RAM offset not yet documented.
only some surface appearance properties; interior item layout nope
use enum values for house info interface

Changes the displayed villager indexes from 1-indexed to 0-indexed to match the game's references.
