Core Plus 2.4.6

	* Minor fixes in the updater including CGI mode support and correctly handling empty
	  "operation" requests.
	* Do not try to parse userconfigs if that model doesn't exist.  Fixes user component
	  updates.
	* Support for the new userconfig features.
	* Changed how the reload method works slightly.  It now sends a 302 header along with the
	  location.
	* If a form action returns the same page that it is currently on, the form system will
	  reload the page instead of trying to redirect.
	* Fixed the smarty issue of SMARTY_DIR already being defined.
