* Generate Let's Encrypt certificate for Duck DNS sub sub domains

* Corrected base_url example.
* Propose reorder of config variables
I've found this docs horribly confusing. `lets_encrypt.accept_terms` should appear at the top of the list as it's the first entered variable. Also this should become `required` as typically `optional` config variables are not displayed in the example config, but it is here.
