4.0

[deepsweet]

• move current CLI to an external package start-simple-cli (node_modules/.bin/start will remain the same)
• create new start-babel-cli that will call start-simple-cliafter require('babel-register') and require('babel-polyfill')
  • no more babel-node explicit dependency
  • cleaner NPM scripts:

"scripts": {
  "start": "start ./tasks"
}

npm start build
npm start dev
npm start lint
npm start test
npm start tdd
npm start cover
npm start travis
