Added the following:
- Observer (it works without any other resource packs, but preferably add one that changes the observer more when active to see changes in the gui)
- Mushroom blocks
- Bell
- All signs
- Lantern and soul lantern
Also added snowy grass, mycelium and podzol blocks. All of the above have their blockstates reflected (except signs since those are separate blocks)
