Qt: Automatically scroll the packet list.

Add an "Auto Scroll in Live Capture" action to the Go menu. It's in the
View menu in the GTK+ UI but it seems to make more sense as a navigation
item.

Use a timeout interval for automatic scrolling. I haven't run any tests
to see if this makes a difference but it would seem that the less
drawing we do during a high speed capture the better, particularly for
remote displays.

Update the x-stay-last icons.

Note that we might want to make prefs.capture_auto_scroll a "recent"
setting.

Mark auto_scroll_live and packet_list_check_end GTK+ only.
