Replace $redirectPermanent with new conf_perm_redirect function. New notices_handler for error/note/success notification boxes. Rename hide_paths to conf_hide_paths. Reorder variable setting, all req-specifc vars are set after initrc and app sourcing, moved request handling code to its own function, this makes us ready to do scgi and other optimizations.
