E-Commerce Address Module and Anonymous Purchases

The address module in Drupal's E-Commerce suite does not allow users that are not registered (anonymous users) to complete the checkout and payment. Thiscan cause loss of business due to users not wanting to register. There has been bugs filed against this, such as: 37220 Anonymous purchases, with patches.Since not everyone is able to apply patches, I am attaching a pre-patched version of the address.module for 4.6, as a zip file.
