Implemented BloodAltar modification with redstone lamp below altar (#1635)

* Implemented BloodAltar modification with redstone lamp below altar

- strong and weak Redstone signal of power 15 (similar to BlockLever)
- activates when crafting finishes and a BlockRedstoneLight is directly below the altar
- deactivates when the next crafting cycle is about to begin

Use case:

- Redstone-controlled automatic ejection of crafted goods

* Removed Docs

* Meta to use 0 for off, 1 for on

* Syntactic sugar & storing value
