Initial Work on Rituals

Added the framework for Rituals, including the automatic registration of rituals using the annotation.
This includes:
- The Master Ritual Stone
- The regular Ritual Stones (all 7 types)
- The Ritual Registration system
- The activation crystal items.
- Reintroduction of the Demon Will Aura (changed saved Dimension ID from Integer to ResourceLocation)

Localization needs to be completed, as well as the implementation of all the rituals.
