When the application is using its D-Bus backend, it is useful to be able to export extra D-Bus objects at the right time, i.e. *before* the application tries to own the bus name. This is accomplished here by adding a hook in GApplicationClass for this; and a corresponding hook that will be called on unregistration to undo whatever the register hook did. Bug #675509.
