Clean up serialization

Browse Source 
* 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.
