title: Laravel 5 config/app.php url setting
body: <p>This issue became apparent for me when using dynamic routes within scheduled emails. The email url's are built with this config setting which apparently is not setup to adjust to the server environment. I am using Forge for production. What is best practice for configuring this attribute? Would I add a variable to env files?</p>
  
  <p>Currently its set as follow:</p>
  
  <pre><code>'url' =&gt; 'http://localhost',
  </code></pre>
