Implemented new Anvil saving format, fixed old chunk saving format.

- Added 'Chunk' Interface.
 - Moved old 'Chunk' to 'OldChunk' and replaced dynamic world height reference with '128.
 - Added 'AnvilChunk' implementing the new anvil chunk format.
 - Added temp fixes to FileMcRegionChunkStore.java, TrueZipMcRegionChunkStore.java and ZippedMcRegionChunkStore.java too allow them to read .mca files.
 - Added the new 'IntArrayTag' since the new heightmap tag wasn't recognized.
 - Moved 'getChildTag' to 'NBTUtils'.
