Creeper woods

Creeper woods would be a new variant of a forest biome, inspired by the location from Minecraft Dungeons. The forest alone would be very similar to normal forest, but to indicate that it's a different biome, it would generate with small stone structures with creeper faces on them (just like in Minecraft Dungeons). The main feature of this land would be that after the nightfall the only hostile mobs that spawn there are creepers. It could be very useful as place to gather large quantities of gunpowder, which is pretty hard to get otherwise. For more technical players it would bring a new, and easier, way in constructing gunpowder farms. It could also be a great opportunity to update creeper's texture to blend in more with the foliage of the new biome.
