gdbus: Add skeleton of DBus.Properties interface 

This interface is responsible for handling properties of all objects in
a given path. Right now it only registers itself, doing nothing useful.
A conversion to this new layout will be done by subsequent patches.

org.freedesktop.org.DBus.Properties spec can be found at
http://dbus.freedesktop.org/doc/dbus-specification.html#standard-interfaces-properties
