Correct detection of missing APPRISE_URL

Installs apprise and allows config of alerting for successful or failed renewals. Currently only supports renewals, not inital issuing. Not necessarily a problem as I'd hope you'd be watching the logs on first run.
I don't love how I create /config/.renew-list.sh. I should readdress this somehow
