From b90995fb4b6d8151df862d40edc8c369d7052cfa Mon Sep 17 00:00:00 2001
From: "W. Trevor King" <wking@drexel.edu>
Date: Sat, 14 Aug 2010 11:28:00 -0400
Subject: [PATCH] Replace .config rather than reconstructing plugins, drivers,
 and UIs.

The previous implementation destroyed any state the plugins, etc. were
holding.  For example, it cleared CommandStackPlugin.command_stack.
