Supports letsencrypt challenges

[arunthampi]

So you can setup LetsEncrypt certificates natively

How do we use this?

[arunthampi]

@devth while setting up letsencrypt, it will provide you with a "challenge" string that your webservice should respond with when requesting the path /.well-known/acme-challenge/:id.

Once you obtain this challenge string, set the environment variable LETSENCRYPT_CHALLENGE with that string, restart your slackin service and follow along with the rest of the letsencrypt instructions.

Btw, if you're using Heroku, they support automatic SSL certs with LetsEncrypt: https://blog.heroku.com/announcing-automated-certificate-management

@arunthampi thanks. I am using Heroku, and saw that announcement, but looks like it's only for paid dynos.

Would be awesome if slackin initiated the setup with LE so it was completely seamless. Still, I'm glad it supports the LE challenge. Thanks!
