Current Glade versions want object IDs to be unique, but currently pavucontrol.glade shares some IDs between the top-level windows. I guess this used to be OK in the past, and the "interface-naming-policy toplevel-contextual" comment in the beginning of the .glade file probably has something to do with this. I want to update the .glade file to be easy to work with current Glade versions, so I will remove the duplicated object IDs. The first IDs to change are the "channelsVBox", "nameLabel", "boldNameLabel" and "iconImage" IDs. These were used by MinimalStreamWidget to create widgets for both devices and streams, but now that the IDs are different for devices and streams, the widgets have to be created by the subclasses. MinimalStreamWidget doesn't need the Gtk::Builder in its constructor any more, so remove that parameter to avoid warnings about an unused variable.
