Add timer to update Online Players list when on the list

Hey there, I noticed since the online player list currently updates when you open it, when on the player list for a while, it obviously doesn't update. So when selecting a player that has disconnected and you go to spectate the disconnected player, it spectates you instead.

This PR makes it so when you open the list, it will automatically update the list every 10 seconds. If you back out of the Online Players menu, it will cancel the timer. If the player you have selected has disconnected, it will back you out and let you know that they disconnected. Not a huge fan of while (true)s, so if needed I can change it to recursion instead.

I can make this a togglable feature if you feel that it should be.

Yeah for some reason this pr has commits that are not mine. I must have mistakenly started this branch from another

If it's too much work to fix this, you could always create a new branch from the development branch, and copy your changes over that you actually want and then just create a new PR.
