Minor file renaming and tweaks
Rearranged the server-side object hierarchy (read more)

This has been a long-running problem for days, but I've finally

AccountData and CharacterData objects:

CharacterData -> AccountData -> ClientData

There doesn't seem to be any issues with it right now, touch wood.
