* Reduced effect of terraforming brushes by 1000%.
* Added new exportImage() function to BasicTerrain which will output a gradient-mapped image of the terrain which can be uploaded to the grid for things like world map images. (shiinnny), will update later with an improved version using the bilinear quad method employed in client terrain rendering. * Rebuild project & build files for basicterrain with System.Drawing dependency. Prebuild updated.
