Huge commit for the Pull-Request.

Added a lot of things:
- Blood Tank
- Teleposition Sigil
- Transposition Sigil
- Cobblestone/Netherrack/Obisidian generation Ritual
- Tree Cutter Ritual
- Pump Ritual
- Altar Builder Ritual
- Block Placing Ritual
- Portal Ritual
- Teleportation System and API Components
- Cross pattern Area Descriptor
- Two reagents and their textures for the sigils’ crafting

Fixed:
- Teleposer not teleporting entities correctly

And probably other things I forgot!
