Subject: [PATCH] Disconnect configChanged() signal from *Settings in
 QWidget-based dtors

Because the QWidget dtor will delete its children first, it is the
responsability of any subclass to disconnect any signal that might be
emitted as a result of a child's destruction.  Otherwise, that signal
could end up attempting to invoke a method on the now-destroyed parent.

The ChoqokTabBar, QuickPost and TextEdit dtors put various settings in
AppearanceSettings or BehaviorSettings, which may end up triggering a
configChanged() signal.  Therefore, all QWidget subclasses that have
connected this signal should disconnect it in their dtor.

(Technically, this is only required of *parents* of the above classes,
so it could be omitted from TextEdit.  Still, better safe than sorry.)
