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.
jp/en/zh -- only english has been translated (duh)
keep in mind this translates the text in the program, not the internal flag names.
not sure if other languages need to be supported; from PKHeX's experience, only spanish is updated (besides jp/zh), as most users speak english or are fine using the program in english.
pls localize villager names and item names for non-english :P -- preferrably automated from raw game dumps
