Fixed: endless blocks from a billboard wall

• Vein miners such as Liteminer, 3x3 hammers, drills and quarries could take items from a shown wall again and again: they hand out a block's drops first and only then try to remove it. The wall refused the removal, so the block stayed and could be mined once more, for the pixel blocks and the wall's own blocks alike.
• While a wall shows a billboard, its blocks are now unbreakable like bedrock, so such tools and machines skip them. For mods that don't check that, the blocks give no items and no experience, whoever asks.
• An enderman can no longer carry off a copy of a wall block, sand or gravel in a wall no longer falls while the wall is shown, and carving a pumpkin pixel gives no seeds.
• Hitting a wall block still shows "protected" right away. After Restore the wall mines as normal again.
