Imports a natural resource texture and applies the resource values to all cells on the map.

NaturalResourceTexture.cs

// Natural Resource Texture Importer
// Imports a natural resource texture and applies the resource values to all cells on the map.
// Texture name and location must be gamefolder/textures/res.png
// Resolution is 512x512
//
// Channel explanation:
// Default value for all channels is 128.
//
// Red (128-0) Oil (inverted)
// Red (128-255) Ore
//
// Green (128-0) Fertility (inverted)
// Green (128-255) Sand
//
// Blue (128-0) Forest (inverted)
// Blue (128-255) Unused AFAIK
// Warning: if the blue channel is below 128, fertile will not work at all,
// also placing/deleting trees will modify the forest value in that area.

I had to use TPB's tip on this..
For some reason, I wasnt able to get the script to load the image until I moved it to localapp.

Off track a little, but is there a way to possibly export the data currently in game as an image?
