- Replace on_rightclick of registered node - Replace on_place of empty hand item to handle sneak-rightclicking to invert rotation - Move registry related things to registry.lua - Fix off-by-one error in nodecore_filtered_lookup - Detect corner interactions, not just edges - Corner interactions rotate by 120° - Add rotate_node function to mimic NodeCore spinmain
