[PATCH]: wpa_gui-qt4: use QCloseEvent handler to close children dialogs

[Kel Modderman]

By implementing a custom QCloseEvent::closeEvent() handler, wpa_gui-qt4 can
close the scan, event history and user request dialogs via File->Exit and the
X on the titlebar.

The current mechanism only handles the closure of other dialogs via File->Exit.
