Only mailables may be queued. InvalidArgumentException in Mailer.php line 314: about centaur

I'll see if I can figure it out after watching the Mailables lesson on Laracasts.

Okay, got it sorted.

1. Make a mailable with a suitable name e.g.

php artisan make:mail CentaurWelcomeEmail

2. Edit App\Mail\CentaurWelcomeEmail to look like this:

<?php

namespace App\Mail;

use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Queue\ShouldQueue;

class CentaurWelcomeEmail extends Mailable
{
    use Queueable, SerializesModels;
    
    public $email;
    public $code;
    
    /**
     * Create a new message instance.
     *
     * @return void
     */
    public function __construct($email, $code)
    {
        $this->email = $email;
        $this->code = $code;
    }

    /**
     * Build the message.
     *
     * @return $this
     */
    public function build()
    {
        return $this->
            ->subject('Your account has been created!')
            ->view('centaur.email.welcome');
    }
}

3. In App\Http\Controllers\UserController and App\Http\Controllers\Auth\RegistrationController replace the following (in the store method and postRegister method respectively)

            Mail::queue(
                'centaur.email.welcome',
                ['code' => $code, 'email' => $email],
                function ($message) use ($email) {
                    $message->to($email)
                        ->subject('Your account has been created');
                }
            );

with the following

            Mail::to($email)->queue(new CentaurWelcomeEmail($email, $code));

(how nice does that look)

4. be sure to make sure you add the following to the top of each controller

use App\Mail\CentaurWelcomeEmail;

5. Do similar for any other existing mail sent by controllers (poss just reset email - haven't looked yet).

6. View mailable documentation here https://laravel.com/docs/5.4/mail#queueing-mail for any other preferential changes.

Would be nice for new users when this is set up by default.

Thanks for your pull request! I made some additional tweaks to the namespace references and the test assertions to get the tests passing. Your mailables have been included in v4.0.2.
