Set trust proxy setting to true

This prevents http/https mismatch when the server is behind a proxy (e.g. Heroku or Cloudflare)

Example error message when trying to connect to a lobby on https://project-f.github.io/F.LF/game/game.html:

Failed to execute ‘postMessage’ on ‘DOMWindow’: The target origin provided (‘http://f-lobby.herokuapp.com’) does not match the recipient window’s origin (‘https://f-lobby.herokuapp.com’).

Failed to execute ‘postMessage’ on ‘DOMWindow’: The target origin provided (‘http://estonia-expo-receptor-screensavers.trycloudflare.com’) does not match the recipient window’s origin (‘http://estonia-expo-receptor-screensavers.trycloudflare.com’).

Thank you so much. You actually tried using the Lobby and it still works?
I think it seriously need some revamp.

Just tested it. I can only get it to achieve 2 fps (ha!) but it works* 🤣

* At least, I could select the players from both peers and start the game successfully.

Oh thank you for the information. Hope I can squeeze out some time to revamp it altogether!
Thank you for your contribution!
