title: Laravel's Input:all() ignores disabled inputs
body: <p>While var_dumping the content of <code>Input:all()</code> with Laravel 4, I noticed that an input generated with the following code is ignored by the framework:</p>
  
  <pre><code>{{ Form::text('departure', 'Departure', array('class' =&gt; 'form-control', 'disabled')) }}
  </code></pre>
  
  <p>But that the following works as expected:</p>
  
  <pre><code>{{ Form::text('departure', 'Departure', array('class' =&gt; 'form-control')) }}
  </code></pre>
  
  <p>I have a good reason to disable the user messing with what is in this input field. Yet I need to save it in the database. How should I do this? Disable the <code>disabled</code> attribute with jQuery when the user submits the form? That's a bit ridiculous, isn't it?</p>
