When not in radio-mode - that is, in the single-connection case - the item currently uses a plain 'Connect' label. That is OK while the item is inside a submenu that describes the device, but we will soon stop using a submenu when a single item can describe the device as a whole. Prepare for that by adding an icon that is shown when in non-radio mode, and include the device name in the label in that case.
