qt: add action "Copy Selection" to the playlist context menu
We have already been providing text/uri-list
when the items are dragged since !5899 (merged), which is useful when the items are dragged to outside the application. In this merge request, I propose doing the same for the global clipboard by providing an option to the user.
I have not assigned Ctrl+C
shortcut for this, because it is already assigned to capture device dialog.
Request review @chub.
