Compatibility with Prettier #2
Description
When using Prettier, most ESLint formatting rules are redundant or may conflict.
Prettier recommends installing eslint-config-prettier to turn off most ESLint formatting rules.
I have attached ESLint and Prettier configurations based on Rooster's (without their project specific rules, at Peter's recommendation), and I have removed ESLint rules that overlap with Prettier. I tested the removed rules to make sure Prettier could handle them. I let the redundant rule linebreak-style": ["error", "unix"] remain because the vsCode Prettier plugin can't autofix the linebreak style.
Discussion of printWidth/max-len and ecmaVersion will be in separate issues.
Note that when using prettier it's also important to have a .prettierignore file.
