Mese post textures should be mostly transparent

The mese post textures are supposed to be an overlay which puts the light texture on the mese post. The texture is overlaid on the regular wood post textures, allowing for many different types of posts, one for each wood.

You just completely overwrite the texture because you leave no transparency in the post area. Unfortunately, that does not work because the post top does not have an overlay (the one provided in default is not used, smells like a bug). Meaning, that all the different-wood posts look exactly the same, except for the top, which has that kind of wood.

To fix, change the post textures to only contain the Light part, leave the rest transparent.
