Removes almost all references to the "magic string" that set the location of the root of the RESTful API
in the Razor server (replacing the string "/razor/api/v1" with a reference to the new "websvc_root" parameter
we added to the Razor configuration).  The only location where the old fixed string appears is in some of the
perftest scenario files in the "acceptance/perftest" folder.  This should greatly simplify the configuration
of the Razor server.  We still need to slim down the configuration a bit more (perhaps moving from the
current setup, which uses two configuration files, to just one), but this is a good start.
