Allow query duplication

When we want to refactor a query, or just try something new, we often want to create a duplication of the query. Currently, we have to copy & paste the query to a new folder, rename it, move it to the old folder and delete the new folder in order to achieve this. Would save a lot of hassle if we could paste the query in its original folder, and ARIS would automatically append "- Copy" to its name.
