Thanks I Have REI

Removing features that might be annoying on unused in modded Minecraft.

Removed features include:

• Multiplayer disclaimer(shown when clicking the multiplayer button, see gallery)
• Experimental warning(shown when creating worlds with mods/datapacks)
• Recipe book(removed not just visually, but the server side logic as well)
• Auto Jump is now OFF by default(removed in 1.5)
• Music is now muted by default
• GUI scale is 2 by default
• Telemetry is disabled
• Outdated resource pack warning screen is disabled(outdated packs are still red, but you don't need to confirm that you want to enable them)

If you know any other thing that should be removed, feel free to open an issue.
