Rather than doing `allowEmpty` as boolean, have separate types and use `std::optional`. This makes it harder to forget the possibility of an empty path. The `build-hook` setting was categorized as a `PathSetting`, but actually it was split into arguments. No good! Now, it is `Setting<Strings>` which actually reflects what it means and how it is used. Because of the subtyping, we now also have support for `Setting<std::optional<String>>` in general. I imagine this can be used to clean up many more settings also.
