* Cleans up food processor code (#73340)
## About The Pull Request
This PR does three things:
- Implements the suggested solution in #63640, items exiting the
processor will remove themselves from the processor list
- ~~Removes an object verb for ejecting the contents of the processor,
moves functionality to alt click~~ kept the verb for now
- Replaces single letter vars, adds autodocs, removes a completely
unused var
## Why It's Good For The Game
Fixes#63640, easier to remove meat slabs you changed your mind about,
and more readable code
## Changelog
🆑
fix: taking an item out of the food processor and putting back in will
not dupe the results when you process them
