Mapblock-granular world operations, transformations and utilities

Features:

Load/Save mapblocks from/to disk
Serializes param1/param2/nodetimers and metadata
Transforms mapblock data on the fly (rotation, orientation, replacements)
Supports caching of the loaded mapblocks for fast in-world placement (mapgen)
Adds a per-mapblock data-storage (get_mapblock_data / set_mapblock_data) with caching

Use-cases:

Custom mapgens with pre-built schematics
Building-mods

Demo:

City mapgen

Chatcommands

/mapblock_show marks the current mapblock with a grid
/mapblock_save [name] saves the current mapblock in <world_path>/mapblocks/<name>
/mapblock_load [name] loads a previously saved mapblock
/mapblock_rotate_y [90,180,270] rotates the current mapblock around the y axis
/mapblock_mark (only available if the worldedit mod is present) marks the current mapblock with worledit
