Add Duplicate/Copy button in the Issues Tab inside a Project

Description - Add duplicate/copy button on the Issues tab inside a project, so you can duplicate requests/issues there. 

Why is this feature important to you - Just as we can copy requests on the request landing page to make entering similar requests more efficient, we would like this feature to be used inside the Issues tab inside of a project. It speeds up the process for entering similar requests / requesting work.

How would you like the feature to work - Enable the copy / duplicate button, should work exactly the same as the duplicate feature on the requests page now. Just enable it for requests inside projects.

Current Behavior - No duplication of requests available on the Issues tab inside a project.
