[TODOs] Cleaning them up

[miranda.conrado]

I'm quite new to MaNGOS and what to learn more about its the struct, so I decided to get some TODOs done.

But when I was looking at Master.cpp, I saw this note:

// There is no Master anymore

// TODO: clear the rest of the code

What does that means? Should I put the functions in World (as the example change was replacing with World variables) or what?

I think the ideia is to put in World, but not sure.

Thanks.
