Re-add delchunks command (#481)
The new command now writes a json file to WorldEdit's working directory with instructions on which chunks to delete, which is read by the plugin/mod at startup and calls the ChunkDeleter. The chunk deleter parses the json and iterates the instructions, backing up .mca files as it goes and overwriting the offset headers with 0 wherever a chunk needs to be deleted. This allows Minecraft to reclaim the space used for that chunk, as well as forcing it to be generated from scratch next time the area is loaded.
