- A test user connecting to the conference via EC.
* config: add feature in `config.json`

I clarified homeserver requirements (i.e. that Element Call needs a homeserver like Synapse but not necessarily Synapse), and also edited some other parts for clarity. I also updated the recommendation to not log in to an existing homeserver based on my new findings that Element Call *may* allow you to log in to an existing HS but log in is unreliable.
The other options are things people usually won't need or want to
set, so just keep it to the basics.
* Rename config sample to match element-web
* Update / simplify build instructions
* Rename nginx config file to differentiate it from EC config
