title: Adding fields to Laravel 5 authentication don't get inserted into the database
body: <p>I've been playing around with Laravel 5's out-of-the-box authentication. When I add fields to the schema and migrate, and then I make them fillable - those added fields don't get inserted into the database, the default fields get inserted but the new ones are blank. The form has been updated to include those new fields. </p>
  
  <p>The console also shows that the form data is being sent correctly.</p>
  
  <p>Am I missing something?</p>
