Json block behaviors Unplaceable

Purpose

Blocks are essentially items that can also exist as placed blocks in the terrain. Whereas items can only exist in inventories, or as temporary drops in the world. The Unplaceable behavior takes away the block's right click to place behavior, making the block functionally like an item.

This behavior is added to blocks that are only blocks for historical reasons but today should act like items. This way, if the world was upgraded, any placed copies of the block before the upgrade can still be picked up, but they cannot be placed back down after being picked up.

The vanilla blocks often uses this behavior in combination with the GroundStorable behavior. That behavior will intercept the right click and instead of placing the block in the world, the behavior creates a new groundstorage block in the world. The groundstorage block is an inventory that shows its contents, kind of a like a chest with invisible walls. So blocks with the GroundStorable property should never be directly placed as blocks (instead they should be stored in groundstorage blocks). As an additional layer of safety, the Unplaceable behavior is added to catch any right clicks that make their way through the GroundStorable behavior, and to document that the block is functionally like an item.
