Title: Some minor tweaks

Add wall/ceiling variant of corrugated roof. They are accessed by explicitly trying to place the regular raillike version onto a wall or ceiling. When placed onto the floor, the normal raillike one is produced.

also, deleted some redundant texture entries
very minor code rearrangement
