Replace all {S,W,B}FALL textures in the levels with their animated
equivalents, and remove {S,W,B}FALL from textures.cfg.
The {S,W,B}FALL were leftovers from when Freedoom had the goal of
being Boom-compatible instead of vanilla-compatible.
Also, rebuild these levels' nodes and reject tables with ZenNode.
Some editors like to save cruft into a wad, along with the map data.
Unfortunately, it is pulled into the build targets by deutex, which
simply includes every lump in each map wad into the final build.
