Changed Bales and Barrels, added Shader

[TheCoCe]

• Bales are split into 2 different Objects now. One for the Bale and one for the small grass sticking out. Both have different Materials with different shaders now.
• Added a sway shader I found on the Unity forums. It's a little weird, we might want to replace it with something own.
• Added normal and specular map to the barrels
