Use and enforce Prettier

[nemtsov]

Let's use https://github.com/prettier/prettier to make the style consistent.

• Use the --single-quote option please (either as an option or as a config; depending on how you implement it
• Make sure the style is enforced when npm test is run

@qm3ster are you, by any chance, interested in taking this one?

Only if I get to do semi: false

Ha! I'll agree to that if you can be certain that anyone wanting to contribute to the source of this repo can recite the Rules of Automatic Semicolon Insertion; and if not, let's just keep semicolons and not have to ever think about those. And I say this after having converted most of my repos to no-semis, seen the issues and regretted having converted them in the first place.

Less code is good; less thinking is better.

You didn't have to recite your history to me, I saw your reply about code style on the other PR and went through your repo to see that it was eslint semis -> eslint standard -> prettier semis.
I was, shocked, appalled, and instead of converting to prettier no semis had to resign to eslint standard-ish
