Helper functions for melonlib

[protocol-1903]

Some things that I noticed weren't included, and wouldn't necessarily be needed for the main mods but would significantly help with addons like pyblock and hardmode (and later pymods that need to modify earlier ones)

The implementation of replace_unlock won't preserve the order of unlocks as the replacement will always be added to the end of the list. Is this intentional?

Also, set result amount and set ingredient amount can currently be accomplished with replace_ingredient and replace_result. I think your implementation could simply call those, if the shorthand is still necessary (I don't mind the addition).

Come again?

This simply removes it from the technology(s) in technology_old and adds it to the technology(s) in technology_new

Missed that, thanks. I'll update the PR.

So if a tech unlocks recipe_a, recipe_b, and recipe_c, and you replace_unlock on recipe a, the replacement ends up at the end of the list. This means if the unlocks were sorted before and the replacement fits the sorting, it is no longer sorted (as far as I'm aware, I don't think they use the order strings there).

[protocol-1903]

The replace() function replaces a single recipe for multiple technologies, not multiple recipes for a single technology. It's for moving recipes around technologies.

Thank you for the PR. Merged.
