[fw-general] Zend_Form_Element_Hash best practices

[Tom Graham]

Hi,

I recently wrote a blog post about how I now use  
Zend_Form_Element_Hash, I hope someone might find it interesting/ 
userful.

I have outlined some issues with the standard approach and how to  
better tackle invalid CSRF tokens.
