Working on it rn check commit "f4e5b84" for changes:

1. Added classes for sender + receiver (same as weave proj)
2. Added url + title updates (rn just stays static make it dynamic) (also requires connecting bg.js + ./scripts/fn.js scripts )
3. Added page switch on connection update ( need to make it stay in memory too ) ( or add a simple loading screen and while loading { check for broadcast msgs ? update and go to connection page : stay on the homepage } )
