#Added temporary registration data for order processing

Temporary registration includes the ShoppCustomer, BillingAddress and ShippingAddress records that are serialized into a 'purchase' meta record for later recall. During the accounts() processing the temporary registration information is loaded and processed into records creating the Customer, WP User, Billing and Shipping records.

The account password is hashed before storage in meta to protect the clear text password from being accessible for more than the order processing workflow.

Temporary registration meta for failed orders are expunged when the cart expires (default 2 weeks) preventing unnecessary access from being granted for orders that are never completed.
Fixed #2522 Included rates of tax settings as part of the sort scoring for tax rates (rates in ascending order)
Button link was using the 'shopp-promotions' slug; 1.3 uses the
'shopp-discounts' slug instead.
