Lazy tags + get / set tiles

Lazy tags means tiles/ents are not translated into the nms NBTBase until it is needed. Should be faster in cases where getFullBlock is called, but nbt is not always needed.
Commands like Copy and Paste, where the input/output are both nms worlds, can entirely bypass WorldEdit translating to and from the WorldEdit JNBT classes.
