Before the patch, we only used to send the DefaultAdapter changed from
one adapter to another, never when there wasn't a new default adapter.

This allows us to remove bad tricks from client.c as well.

Both patches attached. The bluez-gnome patch includes the changes from
the client.c cleanup thread.

Try plugging/unplugging your adapters after the patching, and the
treeview will magically change its contents.

Cheers
