Convert the code in src/core/evaluator.js to use standard classes
This removes additional `// eslint-disable-next-line no-shadow` usage, which our old pseudo-classes necessitated. Most of the re-formatting changes, after the `class` definitions and methods were fixed, were done automatically by Prettier. *Please note:* I'm purposely not doing any `var` to `let`/`const` conversion here, since it's generally better to (if possible) do that automatically on e.g. a directory basis instead.
