+Just a smidgen of compatibility code for twilight forest
+
+- ChunkGeneratorTwilightMixin
+  - Fixes world generation not being cancelled within the shipyard in the
+    twilight forest. TF uses its own ChunkGenerator implementation but it has
+    all the same methods as the vanilla NoiseBasedChunkGenerator so the same
+    mixins work.
