Unify foundation sizes
1x1 is now a 1x1 grid unit for the game 2x2m unit in blender , that you can see using THE Wireframe mode or the special texture in atlas.
Resize and adapt existing foundations accordingly
Unify construction dust, it only appears when building (scaffold variant)
Add 64 foundations from 2x1 to 9x9 and corresponding dirt decals
Add three new scaffolds based on Lordgood's for walls
Rename props to use lowercase names as per art conventions and update the maps accordingly.
Use 0x instead of a b c and d as per the art convention.
Add missing materials tags, and only use special textures when necessary
Template update will be done in the following commit.
