* The 'no to all' option should always be present if there are multiple unsaved
captures across the connections, even if the current connection only has one
capture and so otherwise wouldn't have a 'no to all' option.
* The 'no to all' option will always discard all unsaved captures in all
connections when closing the window, if the user clicks no on the confirmation
of this, abort the close operation entirely and let them decide how to handle
it (e.g. discarding/saving captures in connections individually).
