Biome API: Add decoration flags for underground decorations
Add "all_floors" and "all_ceilings" flags for simple and schematic decorations. Decorations are placed on all floor and/or ceiling surfaces. Decorations are placed before dungeon generation so placement in dungeons is not possible. Add 'getSurfaces()' function to mapgen.cpp that returns 2 arrays of y coordinates for all floor and ceiling surfaces in a specified node column. Move 'getHeight()' checks into DecoSimple and DecoSchematic. Delete 'getHeight()' functions.
