Create different environment block to tile

[PaulHarden]

Different types of ground block types needed:

• [x] Dirt (With grass top like Minecraft? This is the one to be adhered to).
• [x] Rock (Impassable).
• [x] Crate (Destructable, houses items?)
• [x] Thorns (Hazard) - [ ] Water (Done with shader!)
• [x] End goal (small terracotta pot)
