When we close a main window, delete the welcome screen, which in turn

deletes the interface list, which in turn kills off the dumpcap process
it may be running. This should hopefully keep us from leaving dumpcap
processes running in the background on Windows. (Am I the only one
running QtShark on that platform?)
