Revision 951381

A patch from Sascha Rodekamp "Duplicate Product, didn't duplicate the content" (https://issues.apache.org/jira/browse/OFBIZ-3804) - OFBIZ-3804

The Product duplicate function didn't really duplicate the product content, just set a reference to the original content.
When I now change the content from the duplicated product, the content of the original product is changed to.

So here is a patch that dublicate the content, dataresource and electronic text (if exists), too. The result is a true copy of the original product that can be edit without side effects to the original product.
