DevTray bug, can't call static methods via dbus

At some point recently something changed on this machine and DevTray stopped
handling media being removed.  The attached BugReport gives the gory
details, but the error was basically "TypeError: 'staticmethod' object is
not callable".

The attached patch fixes the error by connecting a conventional function to
the DeviceRemoved signal and having that call a classmethod instead.
