feat: Add preferences for "change-recipe-productivity" technology unl…

…ocks (#334)

I was playing over the weekend and needed this to plan out my factory,
based on the discussion in #331 this would be option 3
I had to move the "done" button to the top of the screen to avoid it
overlapping with the levels, and I couldn't quite figure out how to make
a scrollable box

I'm happy to split the PR into the parsing/calculating change vs the UI
change if you think there's a nicer UI to be had :)

(I have some WIP commits that fix the icon rendering too, I'll clean
them up soon)
