Add mappings for most important Extra Cells items (#115)

* EC2 deprecation: Part 1 - Items

Laying the groundwork for absorbing EC2 mappings.

* EC2 deprecation: Part 2 - Blocks

* EC2 Deprecation: Part 3 - Parts

Parts are deprecated.

* set config "replaceEC2" to default true

* API changes to make room for Extra Cells fluid placeholder

* Finish basic item replacement code

- parts work
- items are remapped properly, and converted when they enter the player inventory

* Fixed some storage cell conversion issues

The placeholders did not transfer NBT data properly

* Add handlers for deprecated item cells

Now the placeholder should work automatically in a drive.

The void cell is still a WIP.

* Add more tooltip help and cell handler for void cell

* apply spotless

too lazy to rebase
