Subject: Fix a bug in closeup frame handling.

If, while a frame was in closeup mode, the corresponding client went away,
the ConnectionFrame would get deleted, but still referenced in
ConnectionWindow::_closeupFrame. Naturally, this led to disaster when the same (but really new) frame would be
selected again. QPointer guards against QObject's going AWOL.
