Organize sql/old into respective TDB versions

Clean up /old/ directory and organize updates into their TDB update versions. Done at request of @Aokromes.

- source/sql/old/3.3.5a 
   - /TDB##_to_TDB##_updates/
     - /world/
     - /auth/
     - /characters/
   - /TDB##_to_TDB##_updates/
   - /TDB##_to_TDB##_updates/
   - etc

Only dated files were organized (TDB 38 -> TDB 51). Changes 0861 to 10925 left alone. Files were broken down by changes to world.version table with the first query in each dir being the update to the version table.
