Restructure the app folder

[heron2014]

As a developer I would like to keep my project structure as clear and readable as possible so other developers won't be lost with finding relevant files.

• [x] views folder change into src - follow the reactive standard

• [x] new src folder could look like following:

  src
  |__ components 
  |__index.js

• [x] assets folder (Question - Where is best to keep your css? )

option1:

  src
    |__assets
    |        |___main.css
    |__components
    |__index.js

option2:

  public
    |__assets
    |        |___main.css
    |__index.html

• [x] public folder see has unused file
• [ ] components see is hard to read, add separate folder for each feature, example:
  • buttons to folder buttons
  • feeds is part of the big feature - list of all crushlines (deserve to have separate folder)
• [x] separate babel presets from webpack.config.js L18
• [x] add presets for ES6
• [x] add .eslintrc for consistency
• [x] refactor code to use ES6 (We need to move on from ES5)
• [ ] add hot reloading in webpack.config.js
