Remove js-beautify and improve ESLint config (#590)

Before, there were two linters doing the same thing: linting and fixing lint errors.
Now, there is only one, ESLint. The js-beautify config is merged in the ESLint config
as best as I could do. There is almost no documentation about the rules of js-beautify,
so this was a bit hard.

ESLint was updated to v3, which provides auto-fixing of some rules.

I also checked the new ESLint config against the main webpack repo. This caused some extra
linting errors (~40), but these were all valid violations.
