Bug fixes

Our shipping module has been refined, so the errors you may have seen on checkout (they allowed you to continue, but were unhelpful and often returned incorrect International Rates) should be resolved. The US Postal Service likes to change its code without telling folks.

As well, our checkout process has been refined a bit, and native credit card processing (absent for the past month or so) is active again--no going to PayPal to enter credit card payment (PayPal option is still active for PayPal users, as before). The page load speeds during checkout have improved as a result.
