0.0.3 broadcast server message

Created by: bmarv

architecture-update from server-client program to server-host-client -architecture. The host (=technically another client but with privileged abilities) can send broadcast messages to the other clients using the ws-server. The ws-server is still running on the cli, whereas the host and the client(s) have unique endpoints for the browser. A new layer of communication-management is now introduced, which leads to a very structured form of communication between sender, receiver, their respective ids and message-type, message-content and additional-content. Ws-actions is a module that is outsourced from the index-file to organize the ws-related traffic reg. incomming and outgoing messages and broadcasts.
