Set default namespace to api.php as App\Http\Controllers

[sr2ds]

In my projects, I every change the default namespace of api.php to namespace App\Http\Controllers;.

This make more simple the api.php file to standard Laravel usage. Because, with api.php in the same namespace of Controllers, we don't need 'import' all Controllers with use on top of file, making more simplified this file.

My suggestion is do it as default in the framework to simplify to all.

Thanks
