Add "Server List" button in the Minecraft ESC GUI

This patch adds a new "Server List" button replacing the disabled "Open To Lan" button in the multiplayer pause menu :)

This is a neat feature but currently it will cause endless network exceptions because it is not properly disconnecting before logging into the new server. hook into connect and make sure to disconnect when selection the server

My bad, I assumed everything would work first try lmao. Fix in progress :)

The patch looks like it works :) But quickly switching between the servers may cause a kick with description: "Failed to login: null" not sure whats causing it though. maybe you can find it out?
