Allow For Command Line Resetting of Encryption Key and Data ReEncryption

To comply with PCI compatibility, a system must change its encryption key once a year.  This process can be very time consuming if it had to be done manually.  Magento offers some support in this area, but this Wiz plugin allows the entire process to be scripted.  

In this Pull Request you will find two new actions.  
1. Change the Magento Encryption Key (adds a new random key)
2. Change all of the encrypted data in the database (for the columns you passed into the action).
