Map format changelog

Changes in the map format that are known to me, starting with 900→901.

901

Environment Area

• No Weather Area has been renamed Environment Area.
• This item has gained properties for setting the climate and reflection cube as well as a new flag for disabling precipitation.

Far Model

• The width and height of Far Model areas are now stored halved, meaning a width of 100 units is stored as 50.
• There is a new "far shadows" flag.

Map Area

• Colors are no longer hardcoded, but an index into the map_area_* arrays defined in /def/map_data.sii.
