Store order of configuration dicts

Previously, the order of elements in dicts in the configuration file was
not retained.  The most notable consequence of this is that plugins
would be loaded in an arbitrary order, which may have led to unexpected
or inconsistent results.  Now order is retained, so plugins will be
loaded in the order specified, and all is well in the world.
