Brand New: GUI

There's so many changes...

1. Hud got a complete overhaul
2. All containers got some Tweaks
3. Advancement screen is kinda ready, the unselected tabs still need a retexture but i will do it later
4. Creative inventory and related are complete
5. Toasts are also complete, including the new "now playing"
6. And more things that you will see by yourself!

The galerry is still outdated, but i will work on that in the future. Thanks for reading!
