This PR adds a LANGUAGE lump based on the lump from GZDoom in a classic format, which makes it possible to translate Freedoom into other languages. The Spanish translation was done by Discord user a19684361

Original author granted permission but does not wanted to be credited to further maintain the map, but its a good map to be on freedoom, I'll take the credits so and maintain it if needed.
Both of these chain textures should be usable as decorations in places the player can pass through, but are not complicated enough that the fact that they don't look the same from either side would get lost in the details. I don't see why they shouldn't deserve similar treatment to the diagonal chains (18 and 19).
For when you want an upper area of a wall to have vines but you don't want them to unnaturally cut off at the bottom.
The regular vines have also been tweaked to get rid of some excessive solid colour blocks.
Nothing else in FD's repetoire quite matches the deep, rich, earthy green-brown that these textures have. They're perfect for certain outdoor environments - except in Final Doom they're part of this really unnatural fade-in fade-out animation. This doesn't really matter in FD in isolation but if you try to load a Final Doom-compatible animation definition then the entire intended effect is ruined.
This commit also updates E1M1 to use these new textures.
