Move issues between projects

When trying JIRA, a number of users with access to more than one project have created issues in the wrong project. We would therefore like to have the possibility of moving issues between projects, along with attachments.

I'm thinking about a new permission, named "Move Issues": this permission could be assigned to the jira-administrators group. When an user in the jira-administrators group would view an issue's detail, she would also have a button named "Move Issue": clicking this button would lead to a form with a drop-down menu of projects and a Confirm button. Clicking the Confirm button would essentially create a new issue in the destination project and delete the issue in the original project.

The new issue in the destination project could have sensible defaults, such as Components = None and Version = None; attachments should be moved also, from the directory of the original project to the directory of the destination project.
