V1.3.20.4

This update was focused on the look of the game, as I said some time ago. Here we complete this transition from a game with various visual styles, to a game with homogeneous textures. I also worked better on the map, which I said was still under construction.
As much as the focus was on the visual, also important changes in the gameplay.

Fixed:
// - Fixed double click on duplicate materials in the chest.
// - Fixed spawnable materials.
// - Fixed spawnables where they shouldn't be.

Changes:
// - Decreased speed needed to take fall damage.
// - It is now possible to rotate all collapsible objects.
// - Torch fire slightly altered.
// - Reduction of ammo loots around the map (changed to weapons).
// - You now have up to 10 rounds to get the ammo loot.
// - Reduced foliage in some areas.
// - Added foliage in the city.
// - Bank redone.
// - New buildings created.
// - Now the texture of the radioactive bear is more similar to that of the radioactive wolf.
// - Texture of the remainder of the remainders meshes.
