Add a --verbose flag that uses a more detailed error reporter

@g-plane (the creator of methane) made some cool formatters for ESLint/TSLint:

• https://github.com/g-plane/methane/tree/master/packages/eslint-formatter-beauty
• https://github.com/g-plane/methane/tree/master/packages/tslint-formatter-beauty

Something like this may be cool to add as an optional formatter via a --verbose flag.
