Duplicate an Item

Thanks to the very precious help of @jflatnes, I’ve managed to finish the Item Duplicator plugin. Everything seems to be working fine now, with no more need to edit the core files.

You can find it on GitHub (https://github.com/DBinaghi/plugin-ItemDuplicator).

Comments, suggestions and improvements are all welcome.

Great. Thank you! Finally a solution. Installed and it seems to work fine. I will test ist in the next few days.

Thank you again.
