* Implement command block and jigsaw support
- Command block UI is now fully implemented to match Java Edition.
- Command block minecarts are now supported.
- Command blocks now show the correct type of command block.
- Jigsaw blocks are translated.
Structure blocks can be implemented, but these will be trickier as there are significant GUI differences between Java and Bedrock.
* Add more detail about command block minecart color
* Set PlayerPermission.OPERATOR to allow command blocks to be destroyed
* Fix signs on everything except Paper
* Fix sign line placement
* Update shulker box block entity
