Configured application.
Laravel displays bernly home page in response to '/' request.

Changed ownership recursively to geoffrey:www.
Configured database connection. Added migration to create URLs db table.
Added the Url model.
Can shorten long URL, then display short URL.
Can now redirect a short URL to the corresponding long URL.
Deleted unnecessay files.
Added a url_no_protocol setting to the app's configuration.

This is so that short URLs can be displayed without the protocol, e.g.
bernly.com/a, instead of http://bernly.com/a.
