[Feature] Admin panel

Admin panel for changing room settings on the fly,

Yesss. This will require moving setting from config into more volatile storage. Perhaps a json file. This will also give owners more time in-room setting up as opposed to editing the config file.

@foodbandlt thought I would assign it to you as you mentioned having ideas and stuff for this.

Would be pretty cool to just switch the config file to https://github.com/laktak/hjson-js and send room settings via the /config that already exists. If something is updated, we could just send a wss msg to the pad that reloads the config.
Hjson also supports keeping whitespaces and comments when updating the file.

Dudeeee, that's a large reason why I was opposed to JSON, because of the syntax required. This would be superrrr useful
