v6.0.0

BREAKING Change:

• loadProducts does not check if payment can be made anymore before loading products. This should be useful to show product information in the app. you can still manually call canMakePayments from JS before calling loadProducts.
• Make sure you call canMakePayments before calling purchaseProducts to handle the error gracefully. calling purchaseProduct directly will still error out and you will have to handle the error appropriately.
