Subject: [PATCH] Unset old CA and Cert in system config

This looked odd. Why would we leave behind the old "ca" and "cert" section in $config["system"]?
I guess it would do no harm, but seems confusing for the future to have some unused entries like this remaining in the config.
Should a piece of code be put into the latest upgrade function to clean out these in any current config?
