International Shipping Costs further tweaked

Hey Guys,

Thanks so much to the international customers who have reached out with feedback on shipping costs. Its looks like there were cases where certain product combinations were causing excessively high shipping rates, as their shipping calculations were being added as if they were independent packages, rather than a single box.

I have gone through and overhauled the shipping profile back-end to simplify things down, and it should result in more reasonable shipping rates for those outside the US and Canada. Don't get me wrong, international shipping is still very expensive, but hopefully this will help ease the burden a bit. 

If you're still seeing really high shipping rates, or if you don't see a flat rate shipping option for your country, please contact me and I can take a look into it. 

Thanks again for all your support!
