Bukkit

This update is purely for the usage of TPort for 1.16 with the same features of 1.15.4 (removed message error).

There are a lot of new features ready/being created right now, but that are not in this update yet.

I want the update to be done before I upload anything.

Why this took so long is that I didn't thought that all the new featueres would take so long to make.
