removed worker resurect on exit, unecessary since heroku restarts twice and once every 10 min if worker throws an error the second time
configured the cookie secret key to 256 bits
migrated the response.locals to the index controller instead of making it accessible to all controllers
configured dynamic express routing based on the controllers folder tree
refactored node controllers (now I'm able to specify the type of the controller: GET, POST, etc;), prepared for creating a base reusable controller
