Fixed: Grammar in tooltip of download button

When hovering over the tooltip of an unclicked download button (e.g. in interactive search), it hasn't yet been "added" yet so it should be "add".
And once clicked, the tooltip should show "download queue" rather than "downloaded queue" as "downloaded" implies it has already been downloaded.
