Add linting with eslint for Airbnb style guide

[michalmikolajczyk]

As lead developer, To achieve consistency and integrity across code And avoid code smells I request the addition of a linter like eslint https://eslint.org/docs/user-guide/configuring And support for Airbnb style https://github.com/airbnb/javascript

@ganes1410 #33 broke the project. There seem to be conflicting dependencies, and updates require major version changes of other packages incl. webpack.

Please submit a working eslint config. Basically npm start should compile and serve the project without errors.

@michalmikolajczyk i tried to add the linting.But because some of the npm packages are old.They are not compatible.And that's what broke the project.
