Does the above without the forward declaration, plus:
- add the "default-adapter" property, and property changes notification
- listen to default-adapter changes in the selection widget, and change
the tree model if it changes (so we only show the devices for the
current default)
- remove devices from the list when an adapter is removed, so they don't
appear in the treeview
- show "unknown" in the treeview when a device is of unknown type

It fixes all the UI problems I mentioned in the original e-mail. Next up
would be making the search button work.

About the hcid bug, should GetInfo fail when the bdaddr for the device
isn't available, or should it just give out empty information?

Cheers
