DashSync Issues

[p0wer0xff]

sometime ago, somewhere we broke the compatibility between socket.io versions in flask and js. also, we apparently need a cors header now.

CORS: socketio = SocketIO(app, cors_allowed_origins="*")

socket.io: slim is called min now, and current master works with current socketio-flask server. fixed in prod, will need to update this in the repo soon.
