lots of changes

You will see several commits, here is what i did:

* converted from Dialog to Whiptail

* removed the package list and amended the deb-package stuff to suit. 

* edited the changelog

* since Debian doesnt have armhf and raspbian doesnt have sid or squeeze i edited the workflow. This made it simpler, more error/idiot proof, and smoother

* added shameless plug for ZSH

* fixed a few variable errors (you can email me or details)
