AI/HS/HS2/KK - Backgrounds Set 1

While making some nature scene maps, I had the spontaneous idea to make this mod. Why? Because it's a way better alternative to use those flat background trees, than to use the super high poly 3d models who will only destroy your performance. Those super simple background tree planes (mainly based on trees I had ported earlier) are the better choice to increase the quality of a nature scene when placed correctly, without eatin' up all your precious fps!
