title: Custom layout for ALL errors in CakePHP 2.1
body: <p>How do I use a custom layout for my errors in CakePHP 2.1?</p>
  
  <p>I have looked through the docs and seen various mentions of custom handlers etc but nothing on choosing the layout to use... Any ideas?</p>
  
  <p>In versions of CakePHP before like 1.3 you could create an AppError class but this would no longer work as CakeError is now depreciated and doing anything like that is scorned at according to the docs for new applications.</p>
