- revert CAA checks from !1128 until we have a solid method for getting the correct CAA domain from a host name

Update installer_base.lib.php to get LE SSL certs for the server via certbot or acme.sh before openssl self-signed method upon new installation or existing update; and extend it to other available services (postfix, pure-ftpd-mysql), with additional dhparam pem file, if none exists.

use copy and unlink instead of rename. Might be universally the better option for all environments (i.e. NFS)

updating the website title by the cronjob shouldn't be necessary as it should get updated by the server plugin
