improve use of octave_link
* octave-link.h, octave-link.cc (octave_link::connect_link): Rename
from octave_link::connect. Change all uses. Allow link to be
disconnected. Don't add object to singleton_cleanup_list.
* main-window.h, main-window.cc (main_window::_octave_qt_link):
New data member.
(main_window::construct): Initialize it.
(main_window::~main_window): Disconnect octave_link and delete
_octave_qt_link.
