* Adds a header to serialized data (to make version checking sane). * Removes the duplicate deserialization for `worldedit.deserialize` and `worldedit.allocate`. * Optimizes `worldedit.deserialize` by only deserializing the data once. * Makes some fields optional. * Cleans up the comments and a little of the code style.
