title: Carbon today/tomorrow instead of in x hours
body: <p>I'm using <code>Carbon</code> to modify dates in a project. Now I need get the date as today, tomorrow etc. so I tried it with:  </p>
  
  <pre><code>\Carbon\Carbon::enableHumanDiffOption(\Illuminate\Support\Carbon::ONE_DAY_WORDS);
  
  $date-&gt;diffForHumans();
  </code></pre>
  
  <p>But for today and tomorrow I receive string like: <code>In 5 hours</code> and not <code>tomorrow</code>. </p>
  
  <p>For today i receive: <code>16 hours ago</code> and not <code>today</code>.</p>
  
  <p>The date is from an <code>mysql date</code> column, eg.: <code>2018-05-29</code>.</p>
  
  <p>I read that the needed functionality is currently only available for <code>en</code> and <code>fr</code> but also with <code>Carbon::setLocale('en');</code> i don't receive the needed string.</p>
  
  <p>Using the latest version. </p>
