Colorize analyse results

[goloroden]

What is this feature about?

In the past, when we ran ESLint as child process, there was colored output if something went wrong. Of course, colored output is not an end in itself, but it improved readability of long linting results. Since 12.0.0 we don't have this colored output any more, but it would be nice to have it again 😉

What needs to be done to implement this feature?

• Figure out how to colorize ESLint results
• Enable colored output again

Huh, I actually thought the ESLint results were colored. But I agree that that would be nice to have.

I already added custom formatting for the npm-package-json-lint results which are currently not colored either. We could re-use the format and color in both.

Sounds good 👍
