IAP_method_getProducts

Changes:      tutorials/platform/android/android_in_app_purchases.rst

Replacing the DEPRECATED getSku method with getProducts.
The author of the module made changes, but did not specify them in
the documentation.

Now instead of signals:
sku_details_query_completed
sku_details_query_error

Need using:
product_details_query_completed
product_details_query_error

Now the purchase list is in:
purchase.products

Single item:
dictionary.put("sku", skus.get(0)); # Not available in plugin
Not avaible.
