Schematics and Entities

- Fixed sidedness issue with glue effect packets
- Fixed duplication issue with Schematic tables
- Schematics can now include entities
- Schematicannons can now print:
    - superglue
    - (filled) item frames
    - (equipped) armor stands
    - end crystals
    - boats and minecarts
    - paintings
- Special blocks/entities placed by a schematicannon can now specify custom item requirements (used currently for belts & superglue)
- Fixed superglue not being rotated/mirrored correctly
