New variants of bricks (Snow, Ice, Blue Ice)

Since we recently got Packed Ice Bricks, I suggest adding more variants with different textures.

1. Snow Bricks - Pure white, which makes them more distinct from quartz bricks. The texture is similar to Resin Bricks

2. Ice Bricks - Paler blue, distinct from Packed Ice Bricks. Similar texture to Nether Bricks and Red Nether Bricks

3. Blue Ice Bricks - Deeper blue, distinct from Packed Ice Bricks. Similar texture to Prismarine Bricks or Quartz Bricks. 

Perhaps it could be a fusion of Quartz and Prismarine Bricks texture.
