Adds a transparency slider to have the field items fade so you can see the underlying terrain tile.
Not really optimized (allocates every time), but it should be fine for now.
Make the None item transparent, so that the entire map bleeds through (clear clarity).
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
