Limitations

* The LCD panel becomes unstable when receiving messages faster than 40 times a second. Because of this, I've implemented a queue that will ensure messages are only sent up to 40 times per second. If you fill it with more than 40 commands in a second, then your commands will potentially be delayed. Remember, any backlight commands using tweens will likely send more than 1 command!
