title: phpmyadmin token mismatch for long time idle
body: <p>I installed <code>phpMyAdmin 4.0.4.1</code> on my local develop enviroment, I set <code>auth_type</code> to <code>config</code>. Also I provide authentication requirements by this settings:</p>
  
  <pre><code>$cfg['Servers'][$i]['auth_type'] = 'config';
  $cfg['Servers'][$i]['host'] = 'localhost';
  $cfg['Servers'][$i]['password'] = 'somepassword';
  </code></pre>
  
  <p>But after a while that it is idle, if I click on any link of it , it shows me an error <code>token mismatch</code>, Is there any way that I increase its TTL? or make it alive permanently?</p>
