This just shuffles around the streamwidget a bit. The RoleWidget child class is the
exception, so try and gear things around SinkInput/SourceOutput widgets more to
save repeating the same code too much.
The terminate button is a last resort and shouldn't be promoted in the UI.
This commit hides it behind a right click menu instead.
This also hides the 'Set as Fallback' label in the glade file.
This abandons the combo box approach an instead partially reverts to the popup.
We now display a suffix after the stream title saying " on <device>" or " from <device>"
where the <device> part looks like a hyperlink and, when clicked, shows the popup to change the device.
If there is only one device available, we suppress the whole thing and thus avoid confusion.
This makes the default button work on sinks/sources, allows the drop
down to actually change the sink/source and removes the old menu code.
Some names and such are fixed in the glade file too.
