Add Illuminate\Database support

[knowler]

This would let us create custom DB tables like this:

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;

Schema::create('examples', function (Blueprint $table) {
    $table->increments('id');
    $table->string('name');
    $table->timestamps();
});

Also, Eloquent will work out of the box too, so we can create models:

use Illuminate\Database\Eloquent\Model;

class Example extends Model
{
    protected $fillable = ['name'];
}
