The deprecated metadata gets converted to a proper ItemStackMetaRef.
All keys stay the same except for:
- Cans that use `can_level` now, since they didn't store a serialized table in the metadata before.
- `charge` which is now `technic:charge`, since any item (also from other mods) may have a technic charge which can cause compatibility problems.
Backwards compatibility is kept but going back to older `technic` versions might result in misbehaving circuits.
The low capacity of the prospector turned out to be annoying, while the
other limitations do not substantially detract from fun. Also adjust
recipe to include a blue energy crystal, to explain the source of the
charge capacity.
The new tool will say whether a target block type is present in a
specified region, to allow for more targeted digging. It is deliberately
quite weak, with several limitations: only stores enough charge for a
small number of shots; target can only be set by pointing at an example
node; range is limited; accuracy is less than 100%. Some of these
limitations should probably be ameliorated, but not entirely eliminated,
in the future when we have a better idea of game balance.
The inventory image is only a placeholder.
