Zone Doctor and FF6LE Expansion

Finally I'll try to implement a expanded bank for regular maps to allow full map edits.

Wow, that would be even crazier! Not having to work around space limitations there would make editing these things a lot easier. I had to spend a great deal of time estimating the size of land masses (to avoid going way overboard) and removing things afterwards for Nattak's overworld, and having that part disappear would make it much easier.
