Created index page with route.
url_controller is able to send data to the development database.

* Added a shortened page where user will be able to see their original/shortned url.
User is able to shorten a link and is redirect to the original URL.

* Problems: My test wont pass. I cant get the current_path to load.
Included query string in URL. Added styling.

* Adjusted CSS to match mockups.
* Shortened URL uses request.host to create link
* Used link_to for all links.
