From 19eea41c74154855cb68ee3a1fb41e2ec136b764 Mon Sep 17 00:00:00 2001
From: Michael Meeks <michael.meeks@novell.com>
Date: Wed, 3 Mar 2010 10:36:43 +0000
Subject: clean up the 'express' mode hooks for UI Managers and start to extend
 them to plugins - use a simple one-off boolean on the UI Manager instead of
 exhaustively trying to propagate this information everywhere.
