GObject ≥ 2.26.0 added a nice convenience call for installing properties from an array of GParamSpec. Since we're already storing all GParamSpec in an array in order to use them with g_object_notify_by_pspec(), this turns out nicely for us. Since we do not depend on GLib 2.26 (yet), we need to provide a simple private wrapper that implements the fall back to the default g_object_class_install_property() call. ClutterDragAction has been converted as a proof of concept.
