+Work around a segmentation fault when starting pavucontrol.

+From a98200f2699d453a78c9dfbb85e307bbdb3e3dbf Mon Sep 17 00:00:00 2001

+Subject: [PATCH] Reference the widget before returning it from ::create
+ methods
+
+Widgets (unlike Windows and Dialogs) returned by Gtk::Builder::get_widget*
+start owned by the GtkBuilder object, the idea being that they will get
+added to a container before the scope of the GtkBuilder object ends, and it
+thus automatically gets destroyed.
+
+But in the various ::create methods in pavucontrol, a pointer to the widget
+gets returned, so that it can be added to a cointainer by the caller.
+However as soon as the ::create method exits the GtkBuilder object owning
+the widget, and thus also the widget gets destroyed, and we end up returning
+free-ed memory.
+
+This commit fixes this by making all ::create methods take a reference on
+the widget before returning it, and having all the callers unreference the
+widget after adding it to a container.
