Make `redo_wsdl.py` perfect

Should be able to run once and build / run the server fine. Currently there are still some issues with `wsdl2java` and namespaces, so we have to manually move namespaces and Java files by hand.

We'll have to start parsing or just `sed` replacing stuff in java files when we move them, which can be difficult (might not be fully possible with just regexes), but we'll see.
