Minor Updates

Hey Sophy, I tried to add Figaro (the node version) but was unsuccessful. So, I went ahead and did the following:
* Installed newrelic to package.json 
* Pulled out newrelic.js file to the root folder, added the license key and pushed to heroku (I did not push the newrelic license key to GitHub though)
* Changed "click" event to "submit" event, & wrapped the input field in a form. That solves our issue for autofocusing to our input field after every submit and we can submit using the enter key now

Check it out and let me know what you think :)
