mount-operation: implement org.Gtk.MountOperationHandler

Browse Source 
Use the ShellMountOperation dialogs we have to implement a DBus API
allowing other processes to display them.
Since GtkMountOperation now tries to call into our DBus implementation,
every application that uses a GtkMountOperation will gain integration
with our shell dialogs (but will still handle the actual communication
with GVfs).
