Let's Encrypt Challenge

This is a simple module that allows for a configuration of a Let's Encrypt challenge.

It allows you to set some output for an http://www.example.com/.well-known/acme-challenge/FILENAME url.

It will also look for an actual file present in public://letsencrypt_challenge/FILENAME and if present, it will return the content of that file instead. This could be used with clients that could potentially write the challenge file to that dir. I have had good experience with lego.

If using apache, you will need to tweak the .htaccess file as per #2408321: Support RFC 5785 by whitelisting the .well-known directory.
