Create: Covered

Fixed

• Right-clicking a mechanism with the very block it is already covered with no longer eats a block from the player's inventory on every click. The cover was silently re-applied each time, so a stack could drain away with nothing on screen changing to explain it. Re-orienting a directional cover - clicking again while facing a different way - still counts as a change and still works.
• Swapping a cover for a different block now returns the old cover to the player's inventory (or drops it at the mechanism when the inventory is full) instead of destroying it. Only the new block is spent, the same way removing the cover with Create's Wrench has given it back since 1.0.1.
