- Adds two variants of library ruins: surface (generates in forested biomes) and underground (generates everywhere)
- Adds loot table support to bookshelves
- Adds antique atlas markers for library ruins
- Adds bookshelves and lecterns to the wood type template processor
- Makes bookshelves and lecterns rotate correctly in structure templates
- Generalises most of the methods in WorldGenSurfaceStructure to a new superclass WorldGenWizardryStructure
