natural-mystic-shaders-1.7.0

• Updated the base code from 1.8.0 to 1.9.0.
• The shader now abuses ambient occlusion factor to create more
  shadows, especially on the sides of blocks. It can be disabled via a
  configuration item ENABLE_OCCLUSION_SHADOWS.
• Fixed the direction of reflected sunlight which wasn't parallel to
  the sun.
• Added a thin fog that always affects the scene, not only when it's
  raining. Its color and density is currently constant although it
  should ideally be biome-specific (#9). It can be disabled via a
  configuration item ENABLE_BASE_FOG.
• Grass, fern, and vines now have a waving animation (#11). Other
  plants still don't wave though.
• Fixed the configuration item ENABLE_WAVES not working properly.
• Added a configuration item ENABLE_SPECULAR so you can disable
  specular lighting which might be laggy.
• Added a configuration item ENABLE_RIPPLES so you can disable a
  water ripple animation that appears on the ground when it rains.
