[Innawood] minor updates

[Light-Wave]

Summary

Mods "Some more items are craftable in Innawood."

Purpose of change

Commonly requested features

Describe the solution

Makes nails craftable from bronze
Knitting practice can be performed with plant fiber, thread, and sinew, reflecting how rags can be knitted out of these materials.
Makeshift steam engines can be crafted, added the possibility to craft makeshift air filters using a medium tin can instead of a plastic bottle
rubber cement can be made without a food mixer, instead costing more time and being moderate exercise.
Food processors can be crafted using makeshift transformers
RV kitchen unit can accept a craftable frying pan as a component rather than only an uncraftable version, thus making the RV kitchen unit craftable.
Implementing item group overwrite, thus (hopefully) fixing issues where players would find inappropriate items in spider pits, while foraging, and in dinomod nests.

Describe alternatives you've considered

The RV kitchen unit recipe change would probably fit in mainline. But I'm too lazy to put it there.

Testing

Booted up the game and made sure all recipes were there and looked all right.
Teleported to a spider pit and noted there were no inappropriate items.

Additional context

As far as I can tell, the errors are related to density, and unrelated to these changes.
