Detangle the code that manages the interface list on the welcome screen:

    fill_capture_box():

	if there are interfaces on which to capture, constructs the
	interface list, otherwise destroys the interface list and puts
	up a message.

    update_capture_box():

	updates the interface list to reflect current reality.

    welcome_if_panel_reload():

	if there is an interface list, and if there are interfaces on
	which to capture (so that we still want that list), updates the
	list by calling update_capture_box(), otherwise creates or
	destroys it by calling fill_capture_box() (as either it doesn't
	exist but now needs to or does exist but needs to go away).

Have refresh_local_interface_lists(), which re-fetches the list of local
interfaces and updates every interface list that includes local
interfaces, and refresh_non_local_interface_lists(), which only updates
interface lists that (also) include interfaces other than local
interfaces (such as pipes and remote interfaces).  Call them in the
apprpriate places (if we know the list of local interfaces has been
updated, call refresh_local_interface_lists(), otherwise, if we know
interfaces other than local interfaces have been added or removed, call
refresh_non_local_interface_lists()).

Don't have any routine that updates the interface list for one widget
update the interface list for any other widget; leave the global
updating of interface lists up to refresh_local_interface_lists() and
refresh_non_local_interface_lists() - only call one of them if any
interface lists are to be updated.
