This code lets you show something like this:
+-----
| TOPIC MUTES [undo] [x]
|
| You muted stream Foo, topic Bar.
+-----
And then you configure the undo behavior, and
everything else is controlled by the widget.
Codewise it's a singleton widget that controls the DOM inside
#feedback_container, which gets served up by server.
