Users are now tracked, doesn't work on first connection, loginButtons show instead. I suspect this is due to all meteor users being removed on server startup
All connected users are displayed in a list.
All along accounts.createUser should have been outside a method
A user can be identified by their connectionId, and will be removed if the default flag is not changed from true.

watch out for functions, some need to be started with = and some without, see onConnection in server.
