Purchasing from Hong Kong

[st8st8]

Hong Kong has no postal codes, so when Django Oscar Paypal calls back into Oscar from a purchase made by a Hong Kong user, I get this error.

Internal Server Error: /checkout/paypal/place-order/490/

Oscar has blank=True set for postcodes, so it doesn't require them. My best guess is that instead of the empty string, django-oscar-paypal passes None for the postcode.
Either way, this is a bug and I'd happily accept a pull request for it.

@st8st8 I got the chance to add a commit to #113 that, if my analysis is correct, should fix your issue. This will be merged and released next week.

So I'm closing the issue; please re-open if the issue still persists. Thanks again for reporting.
