title: Laravel: How to add a word for a language in RUNTIME
body: <p>Well the title is pretty clear.</p>
  
  <p>I want my USERS to add custom lines in Laravel. Obviously they should not go open <code>messages.php</code> file and edit it :')</p>
  
  <p>Imagine that user wants to create a category. But they want to name that category in several languages. </p>
  
  <p>Can I do this in Laravel? if not what's the best way?</p>
