Fixing bug...

- Maybe fixed weird lobby member glitch?
- Fixed user staying in lobby member listing after a kick
- Fixed friends list UI not updating when a user joined/left a lobby
- Fixed accepting/denying friend invites
- Fixed unsupported browser message showing all the times
- Fixed user avatar pulling wrong URL
- Fixed not being able to reinvite users for 3 minutes (can reinvite
every 15 seconds now, need a way for users to block invites from a
player for a duration now?)
