Jay S. Bryant 0395353c4b Move config-reference to configuration
It was discovered today that the 'config-reference' directory
was supposed to have been renamed to 'configuration'.  The doc
team was expecting it to be at that location so that they could
automatically link to it from contributor/index.html .

This patch just moves the directory.  I am going to be submitting
a subsequent patch that properly sets out the framework for the
additional directories so that we don't have addition problems
in the future.
