Fix normal map orientation for Terrains
- Terrains use "OpenGL" style normal maps, while 3D assets use "DirectX" style normal maps. So, fix all of the normal maps I can find with incorrect style normal maps.
- Set most terrains to angle="0" for more accurate shading. This negatively affects "tile" terrains, which we want to have a 45 degree angle, but helps all other terrains. aegean_paving_01 is an example of a permanent fix for this, which I will work on with Stan for R28.
- Adds a couple of really nice paving terrains for a new "Italy" terrain set.
- Adds a nicer "furrows" normal map for farmland terrain
- Improved persian city tile normal by @wraitii
