Is your feature request related to a problem? Please describe.
So I like to use both Ex Nihilo and Tetra, but the two have relatively poor compatibility together. In particular, they both have hammers with overlapping recipes, and ex nihilo adds a number of tools that cannot be repaired, upgraded, or customized via Tetra.

Describe the solution you'd like
Create a compatibility mod that will remove the ex nihilo hammer when Tetra is present, and add it's functionality to the Tetra hammer. Add a tetra Crook with all the usual tetra functionality, and allow ex nihilo crooks to be upgraded to match.

Describe alternatives you've considered
I have also submitted this as an issue with Tetra: mickelus/tetra#436

Closed due to comments made in tetra repo.
