Fakename(unofficial)

 After installing the mod, you can easily change your display name in the game. The change will only apply to the world/server, so the modification does not permanently change your nickname. To change your name, simply enter the command /fakename set -- this is an unofficial update, I just needed this mod on my new Forge, so I updated it to make it work well and decided to share it. I'm not the author of this mod, I just slightly modified it.
