Use tooling lint repository for linting and integrate eslint

This uses `@exercism/eslint-config-tooling` for linting now. It also is a WIP to integrate `eslint` as analyzer, until we have solid integration in the web experience.

Currently, when a solution contains `reduce`, we _explicitly_ bail out early. The following two examples should be considered _approvable_, but **not** optimal. Both should come with a hint. ``` const...

**Describe the improvement**: When a solution has `+expression` instead of `Number(expression)`, and it's _otherwise optimal_, we want to give a specific message. It should still _approve_, but add a message...

**Describe the improvement**: When the following main method is provided, the analyzer bails early: ```javascript export const value = arr => { return +(COLORS.indexOf(arr[0]) + "" + COLORS.indexOf(arr[1])); }; ```...

Improve two-fer: recognise re-assignment

**Is your feature request related to a problem? Please describe.** When a solution is provided with a re-assignment, the analyzer bails out of a lot of code paths. ```javascript export...

**Describe the improvement**: When an _optimal `map`_ solution is provided, the analyzer should `approve` but provide a comment that allows them to _continue_ the path. ``` Perhaps there is a...

Anything we write to a file called `analysis.out` (in the solution directory) will be made available to us later for manual inspection. If the `-c(onsole)` flag is not given and...

Currently there is quite a bit of code that is obnoxious because of `node.fs`. Instead, we might want to use [`shelljs`](https://github.com/shelljs/shelljs) and have a lot of this be handled by...

Typescript not working well in editor

Students are now passing solutions that are not valid TypeScript, because CodeMirror isn't actually running TSC. - Should we change the test runner to also run tsc? - Is it...
