No warning or error when a wall has an undefined texture.

[Adam Biser]

Using this tile definition, the engine will have a HOM-like effect, but I don’t see a warning about missing textures. Might be useful to have one if possible.

tile 1
{
    texturenorth = "BLAH";
    texturesouth = "BLAH";
    textureeast = "BLAH";
    texturewest = "BLAH";
}
