Django-paypal-express-checkout

- BACKWARDS INCOMPATIBLE CHANGES!
- field renamed from payerID to PayerID, which is what PayPal returns. You
might need to update your templates
- Added redirect parameter to SetExpressCheckoutFormMixin - this enables you
to use this form with AJAX calls as it will only return the redirect URL
instead of a HttpResponseRedirect
- Added skip_confirmation attribtue to DoExpressCheckoutView. If you set this
to true, the confirmation view will not be displayed, instead it's POST
handler will be executed, just as if the user has clicked the "Confirm"
button. This allows you to save one click during the checkout process.

- Fixed wrong fieldname in model admin's search_fields

- Added user_email to all the other admin sites.

- Fixed critical bug in SetExpressCheckoutForm

- Added user__email to PaymentTransactionError admin

- Some fixes for the DoExpressCheckoutForm
- Made item field on PurchasedItem model optional
- Added CUURENCYCODE setting
- Added identifier field to Item model - this helps to select items in the
forms.
- Aded post_transaction_save method to checkout form.
