feat(module): compatibility with nuxt v2 (#111)

BREAKING CHANGE: This module is no more compatible with nuxt versions older than v2.0.0
Update `nuxt` devDependency to v.2.0.0

Compatibility with webpack v4
Add `FriendlyErrorsWebpackPlugin`
Add `@nuxt/friendly-errors-webpack-plugin`, `extract-css-chunks-webpack-plugin`
Use `consola` instead of debug for logging, improve messages
Add `webpackbar` in production, improve logging
Upgrade husky, move config to its own key
Remove `.yarnrc` engine compatibility fix

Replace `nuxtent` by `@dinamomx/nuxtent` dependency, temporary fix, see nuxt-community/nuxtent-module#190
Fix `nuxt-netlify-cms` dependency to `file` protocol
