WHA-Magic!

Added Integrated initial spell simulator recognition engine into Minecraft. SpellPaperItem to allow players to draw sigils and signs using a UI. Initial dictionary of element sigils and signs based on the Witch Hat Atelier magic system. Gestural drawing interface with ink rendering. Fixed Fixed an issue where the circular ring stroke was incorrectly classified due to its center of mass, which caused any spell with a ring to default to a Wind spell. Fixed an issue where large core sigils (like the Earth sigil) were improperly fragmented into "sign" strokes. Improved stroke identification logic to measure average point radius rather than stroke center of mass, vastly improving recognition accuracy for complex sigils.
