app: add gimp_container_editor_bind_to_async_set() 

... which takes a GimpAsyncSet and a message, and shows a
GimpBusyBox with that message, instead of the container view, while
the async set is nonempty.

We're going to use this for font-loading indication in font views,
such as in the fonts dialog.
