Home install setup script now allows to install apache or nginx (one entry was added in the config file)
A global daily script is now launched for letsencrypt certs renewal and backup on an external device. If you install several zot hubs/instances on the same server, only one script will remain for those two tasks, as they do not involve specific commands for each domain. Each hub/instance also has a daily update script (using util/udall) that is launched by the global script (using a 'for' loop).
Tests were made on a fresh and clean Debian 10 (VPS), installing two Zap hub/instances using the same webserver. Everything worked fine, both with apache and nginx.
