Jasper St. Pierre 10e857cebe Update copy/paste code from upstream
This includes a rename from the G* namespace to the Gtk* one, which
will help us with introspecting this code. Note that this removes
some of the custom code we added to GActionMuxer to relay event times
to the remote action group. We'll add this back soon.
