Represent current game mode on the keyboard

[BrailleBennett]

Problem/Use Cases

Players are not quickly able to tell what game mode they are currently in. This would be a great small but very important piece of info to add.

Feature

Add a key that glows a different color depending on the game mode. Green for creative, yellow for adventure, blue for spectator, and shades of red that get darker and darker the harder your survival mode is set from easy all the way to hard core.

Alternatives

Incorporate this information into the background of the keyboard along with the already planned biome info.
