Continuing from the previous patch, this patch renames more objects in
pavucontrol.glade to get rid of duplicate IDs. nameLabel and iconImage
actually weren't any more duplicates, because the previous patch renamed
the corresponding IDs for devices and streams, but the card related
objects were renamed nevertheless to be more descriptive and consistent
with the IDs used by the device and stream widgets.
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.
