title: Laravel 4 - retry all failed jobs
body: <p>In the laravel 4.2 docs it is said that if I want to retry failed job from the failed jobs table I should do:</p>
  
  <pre><code>php artisan queue:retry 5
  </code></pre>
  
  <p>where 5 is the job id.</p>
  
  <p>How can I retry all failed jobs at once?</p>
