Embed Etherpad Lite pads into Discourse posts using the Onebox mechanism.
After installation just insert Etherpad Lite links like https://beta.etherpad.org/p/embed-me-into-discourse into your Discourse posts or comments. The Etherpad will be embedded using the famous and beloved IFRAME tag and is fully operational.

The configuration line you have to add to your container's app.yml file looks like:
- git clone https://github.com/fuerst/embed-etherpad-lite.git
The plugin uses the "Brand new plugin interface" to change URL's like http(s)://domain.tld/p/pad-id into HTML code like <iframe src='http(s)://domain.tld/p/pad-id'></iframe>.
That means it also changes your non-Etherpad URL's which looks just like Etherpad Lite links. Please drop me a note if you got a better idea about how to avoid this.
