[Outsider] - Create a database dashboard

[AntonioObra]

Create a modern version of adminer, that will be integrated in Abyss by going to the route abyss.test/database, where you will be able to see your database, play with it, run migrations, run seeders, inserting, updating and deleting your data, with the logic you created in the code.

This should be a replacement for any PaaS db management, while being deeply integrated with Abyss.

The route for abyss.test/database, and all of the future predefined routes should be set in a new file inside of the routes folder called app.php so you know exactly where that route came from and can easily change it like you would change anything else inside of the framework. This goes by our mission to have a framework as transparent as possible so you know exactly where everything came from and why it behaves the way it does.
