Safe Preview

Most of the time, the blocks you see are "fake." The preview relies on packets, meaning the blocks aren't actually present. They're placed using WorldEdit/FAWE only after you complete the edit. For instance, if I break the floor under mobs during a preview, they won't fall.
When I finish doing the edit, they finally fall to the floor, that means the blocks are actually placed/destroyed in the world.
